Onion Omega2 Breakout

Onion Omega2 Breakout

My Omega2 Onion shield, using a AMS1117 for 3.3V and CH340G for USB to serial. Kind of ugly soldering here as I didn’t have a tip for the syringe to dispense solder paste, so I just smeared it all over and hoped it reflowed well. It kind of did, but I had a solder blob short on pin 14 +15 on the CH340G, so I just lifted those two legs off the board. I was so eager to get this board tested that I forgot to check that I had these 2mm pin headers. I had just enough to get this thing tested. Time to order more 🙂

Onion Omega2 Breakout

Simple breakout board using the dirt cheap IC’s CH340G ($0.30/each on ebay) for Serial and a AMS1117-3.3 ($0.025/each) for power. Breaks out all pins from 2mm to 2.54mm headers. Plugs nicely into two small breadboards for prototyping.

HydraESP32: HydraBus and ESP-32S

The Espressif ESP32 features a 32-bit 240 MHz dual core processor with Wi-Fi and BLE. HydraBus created this shield for ESP-WROOM-32 or ESP-32S.

HydraESP32 v1.1 Rev1 with ESP-32S is alive

This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.

Mike Rankin created this board with a tiny OLED display controlled by an ESP8266:

MicroUSB powered ESP8266 OLED Board

I created this design as a challenge to make a design under 1″ x 1″ in size.

https://0miker0.wordpress.com/microusb-powered-esp8266-oled-board/

The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.

Mike Rankin created this adorably small WiFi-connected color OLED board:

ESP8266 Color OLED

I’ve been keeping an eye on the SSD1331 library to see if it would eventually work with the ESP8266 wifi modules. I noticed the support for it appeared one day with the Adafruit library so I tried it out on my Adafruit Hazzah and success!

Charles McClelland created a Wi-Fi Connected Teensy Data Logger with GPS and Accelerometer:

Wi-Fi Connected IOT Thing

The basic idea is that this board will connect to GPS, obtain a GPS fix and report its location to Ubidots.

Ubidots can then display this information in a number of ways including showing the location and the number of times the sensor had been moved that day
