- wallet development platform :)- badge / wrist band holes ( wearable )- compatible board with micropython (CircuitPython) - extra thin Display from here https://hackaday.io/project/18014-5-alphabets-charlieplexed-matrix-display-22x5- I2C header for extra sensors ( TOL distance, pressure, compass, gas )- DS3231 > precise RTC- SHT21 > temperature, humidity- BME280 > temperature, humidity, atmospheric pressure ... maybe BME680 soon- RGB led- Power led- 3+1 buttons- micro USB or PCB USB- sd card reader - CR2032 battery optional power supply or DS3231 backup- buzzer- Enig gold 2mm PCB boardEasy program in python, just plug in to USB, you can see mass storage device with .py filesjust change program in notepad ... amazing simple.Or write sketch in arduino IDE :)
People have asked us to create a wearable biometric data gathering device (see our philometer project) and this board would be really fun to build around. Nicely done!
about 100$ 20pcs ....20$ for 2mm, 20$ ENIG, 25$ steel stencil (soldering lot of led without reflow is suicide ) and rest is for boards. Boards shipped and awaiting soon delivery :)
where did u buy the atsamd21g18?
