The nRF9160 Feather Is Now Served

Low-power shutdown, built-in 4FF SIM card slot, flexible power supply, and more.

I was a complete failure. My prototype wasn’t working. I spent at least an hour trying to rework a frustratingly large LTE module on an impossibly small circuit board.

It wasn’t going to work.

So I went back to the drawing board. I poured my years of hardware experience into a tiny form factor.

The end product?

Something smart. Something with LTE, NB-IoT, and GPS. Something anyone could get started with right away.

And thus, the nRF9160 Feather was born.

I need your help! 🙏

To make this campaign a reality, I need your help to meet our minimum order quantity of nRF9160 Feathers. Without that, we’re dead in the water! Head on over to the campaign page to reserve yours.

For those of you who’ve already committed, I thank you from the bottom of my heart. I can’t wait to get the nRF9160 Feather into your hands!

P.S. Huge thanks to Hackster and GroupGets for making this happen. You guys and girls are great. ❤

iCEBreaker FPGA: new video streams and new content

An update from our Dorkbot PDX friend, Piotr Esden:

iCEBreaker FPGA: new video streams and new content

iCEBreaker Production

As you read in our last update in November, we finished fulfilling the campaign, but that does not mean work on iCEBreaker has stopped. We keep producing iCEBreakers and Pmods to keep 1BitSquared US and 1BitSquared DE, as well as Crowd Supply and Mouser, stocked.

For those of you who are patiently waiting for your shipments, don’t worry. A package with additional inventory is going out to the Mouser warehouse today!

Continuing Work on iCEBreaker

We are continuing work on new examples and additional iCEBreaker hardware. If you are not following 1BitSquared or Piotr on Twitter, you might have missed some stuff that Piotr is working on. Since January, Piotr started streaming on Twitch on a fairly regular basis. You can follow him on Twitch and be notified every time he goes live. Piotr is also announcing upcoming streams at least a day in advance on Twitter as well as on the 1BitSquared Patreon page.

As a result of the Twitch streams, we’ve had a few interesting new developments for the iCEBreaker platform. A few weeks ago, we published Litex RISC-V SOC generation examples that you can find in the iCEBreaker GitHub Organization. Piotr gave a Twitch stream presentation about the build system and how to use it. You can watch the stream Archive on Twitchdiode.zone, and YouTube. This example gives you the foundation to create your own SOC for the iCEBreaker, start adding your custom hardware to the RISC-V core, and program it in C or Rust. We are also working on MicroPython and maybe even CircuitPython support in the not too distant future.

Upcoming Twitch Stream

Piotr has scheduled a Twitch Stream for Tuesday, April 13th, 2020 at noon PDT. He will be working on a new Pmod for the iCEBreaker that will allow us to connect NES or SNES controllers from two very popular 8-bit game entertainment systems. 😉 That same Pmod will also contain a stereo audio output. This Pmod together with a DVI output, LED Panel output or VGA output will be an ideal combination to recreate old or build new custom game consoles and a wide range of emulations, for entertainment, preservation, and education.

electronics-lets-play-stream

If you are curious when the stream will happen in your timezone you can either check on Twitch itself, as there is a countdown timer till the next stream below the video streaming window, or you can check timeanddate.com.

Keep Supporting our iCEBreaker work

If you like to see continuing work and content creation for the iCEBreaker platform, and you already have all the hardware you need, then consider supporting us through Patreon. We keep adding perks for Patrons, like KiCad panel templates and behind the scenes news. We have a few very generous supporters that make the Twitch streams possible, but any additional support is appreciated.

Stay in Touch

And don’t forget, the continuing development and support for iCEBreaker keeps on rolling on the 1BitSquared Discord server, and iCEBreaker forum! So join the fun and show off your iCEBreaker projects! 🙂

Stay safe and healthy,
Piotr and Danika

CircuitBrains Deluxe

Easily Add a Powerful Microcontroller To Your Next Project

CircuitBrains Deluxe is the smallest soldererable ATSAMD51 module. Skip on all the tedious work of adding a 32-bit microcontroller to your next project. We’ve taken care of the tough work of pin mappings, power & decoupling layout, clock, flash, assembly, bootloader, and firmware. All you need to do is drop a footprint into your next PCB design project, connect your peripherals and USB connector, then solder it on and write your code.

Just Solder It On

Save time and frustration on your next project. We’ve taken care of the finicky fine-pitch surface mount assembly for you. CircuitBrains comes in an easy-to-solder castellated module format. You can either incorporate it into your project PCB design, or solder wires directly to it via the extra holes in each castellated pad. We’ve also made it easier to hand solder these modules by including a larger “hand solder” PCB footprint for your design.

Add Some Power to Your Project

The core of CircuitBrains Deluxe is the Microchip ATSAMD51J19 32-bit ARM Cortex M4 microcontroller, which can run up to 120 MHz. In addition to a powerful microcontroller, each CircuitBrains Deluxe module has 8 MB of Quad SPI flash onboard. You’ll have plenty of space for your project code and media files.

Easy to Program

CircuitBrains comes preloaded with CircuitPython. Who doesn’t love Python on microcontrollers? Plug your device into USB, modify your code, and see the changes take effect as soon as you hit Save.

Small Form Factor

CircuitBrains Deluxe won’t take up a lot of space. It was designed to be used in small projects. At just over 1 square inch (29 mm), there aren’t many places this thing won’t fit into.

Open Laptop Soon to be Open For Business

How better to work on Open Source projects than to use a Libre computing device? But that’s a hard goal to accomplish. If you’re using a desktop computer, Libre software is easily achievable, though keeping your entire software stack free of closed source binary blobs might require a little extra work. But if you want a laptop, your options are few indeed. Lucky for us, there may be another device in the mix soon, because [Lukas Hartmann] has just about finalized the MNT Reform.

Since we started eagerly watching the Reform a couple years ago the hardware world has kept turning, and the Reform has improved accordingly. The i.MX6 series CPU is looking a little peaky now that it’s approaching end of life, and the device has switched to a considerably more capable – but no less free – i.MX8M paired with 4 GB of DDR4 on a SODIMM-shaped System-On-Module. This particular SOM is notable because the manufacturer freely provides the module schematics, making it easy to upgrade or replace in the future. The screen has been bumped up to a 12.5″ 1080p panel and steps have been taken to make sure it can be driven without blobs in the graphics pipeline.

The DomCo Electronics, Inc. ESP8266 AC Power Switch is everything you need to get started with controlling AC mains from an ESP8266. We know dealing with AC can be intimidating for people at times and we wanted to simplify the process of making your own IoT device.

Everything you need to control a 100-240VAC 50/60Hz load is built right onto the board. Simply solder on a power lead and socket of your choice to the Power Switch and the on-board code can get you up and started in minutes. (We have a USA power tail and socket in the optional extras below.) No more needing to wire up an ESP board, a Wall wart, an IoT Power Relay (Power Tail), and a bunch of wires just to control your light or coffee maker.

Miasma: Classic Dual Voice Eurorack Synthesizer Module

Miasma is a pure analog oscillator module based on the Curtis CEM3340 chips used in legendary ’80s synths, with new & innovative signal patching:Screenshot from 2018-02-17 12-51-02.png

Miasma: Classic Dual Voice Eurorack Synthesizer Module

We designed the Miasma Voltage Controlled Oscillator (VCO) to bring that classic ’80s synthesizer sound back to Eurorack modular systems. We just couldn’t find any currently available oscillators with the sound textures and capabilities that we wanted, so we had to design our own; and now you get to own one as well.  

There are many unique capabilities built into Miasma that you won’t find in any other oscillator module, like the built-in patching and cross modulation structures that make Miasma so flexible in your rack. However, it’s all about the sound – so let’s start with some Miasma audio samples, before we go into the technical details of how we make that sound possible (best listening with Headphones!)

Reflowduino: Circuit Board Assembly for Everyone!

Reflowduino is the first completely open-source, Arduino-compatible reflow oven controller of its kind that enables practically anyone to assemble their own beautiful circuit boards at home!

Reflowduino comes loaded with features, all in a compact Arduino-compatible package, with full documentation, example code, demo app, and comprehensive wiki on Github.

ecriw1wwk9mpio5pmbz4

Reflowduino is designed to be extremely easy to use! The general concept is to switch the power of the appliance on or off with a solid-state relay as shown below, measuring the temperature by placing the thermocouple tip inside the oven during the whole process.

If nothing else, please share this campaign to your friends, family, and anyone who might be interested on social media! Remember that every view counts for me, and I’m depending on you to make this happen!
