The Raybeacon is full-featured nRF52 based wearable, ultra-low power, multiprotocol development board designed for variety of embedded applications. Due to modular design, the device can be used to build your own production-ready appliance with minimal hardware modifications.
Key features include:
Coin sized – the board is only 25 mm in diameter
Works from a single CR2032 / CR2025 3V button cell
Nordic nRF52 high-end multiprotocol SoC supporting Bluetooth 5.x, Bluetooth mesh, Thread and Zigbee; of your choice:
nRF52833: Cortex-M4F 64MHz, 512KB flash, 128KB RAM, Bluetooth® 5.1 Direction Finding, 105°C temperature qualification
nRF52840: Cortex-M4F 64MHz, 1MB flash, 256KB RAM, Bluetooth® 5.0, ARM TrustZone® CryptoCell cryptographic unit
Automotive grade BOM components – ready for harsh environment
2 x tactile buttons IP67
1 x RGB LED
1 x infrared LED (850 nm) 0402 size
Socket for NFC flex antenna, compatible with Nordic FPC antenna and Liard 0600-00061. Can be configured as extra 2xGPIO.
Programmable through SWD port (removable Tag-Connect socket, on-board solder pads)
1.27mm pitch 2×4 receptacle to connect custom extension boards:
6 x GPIO ports
1 x 12-bit ADC input
pass-through VDD and GND pins
2.54mm pitch 1×8 pin header for fast breadboard prototyping; can be reused as 1.27 to 2.54 adapter
USB interface (on-board solder pads)
Minimal fabrication cost due to simple, two-layers only design
We really like this “Back to the Future”-themed Flux Capacitor badge add-on (SAO) by Squaro Engineering made with our “After Dark” service (which features clear soldermask on black fiberglass substrate).
The Ricoh GR II has a remote interface. But like most modern cameras the interface is terrible. It’s a WiFi Access Point that uses a web app. And because most modern phones are terrible, this means you have to juggle between WiFi that doesn’t provide an internet connection and a web app that kinda requires it. The Ricmohte uses the ESP32s WiFi to connect to the camera and issue commands.
And finally, receiving the biggest applause was Linux-on-Badge: this team used all the badge hacking tricks in the book. The hardware component was a 32 MiB SDRAM cartridge by [Jacob Creedon]. The default badge SOC FPGA bitstream was entirely replaced in order to support a minimalist Linux. Much of the development was done on [Michael Welling]’s computer, guided by the precedence of a LiteX project putting Linux on the Radiona ULX3S. This is a true success story of Supercon collaboration as the team (including [Drew Fustini], [Tim Ansell], [Sean Cross], and many others) came together and worked late into nights, drawing from the massive body of collective expertise of the community.
Our “After Dark” service is the same cost as our 2 layer purple PCBs: $5 per square inch, which includes three copies of your design. For example, a 2 square inch board would cost $10 and you’d get three copies of your board. You can order as many copies as you want, as long as they’re in multiples of three.
Finally got around to soldering these up. Used my hot glue method to also fill the hole on my heat resistant mat that hot glue won’t stick to so it cooled down completely flat with the board surface. I’ll have them with me at @BSidesAugusta tomorrow. #badgelifepic.twitter.com/lgoqNISEJ8
