Replacement board for a cheap chinese U8/U80 watch.
BigCorvus/PAH8002
Optical heart rate monitor found in the SMA-Q2 smartwatch.
BigCorvus/PulseSensor-for-SMA-Q2
The Pulse Sensor from https://pulsesensor.com re-designed to be made on a tiny flex PCB to replace the HR sensor of the SMA-Q2 watch.
BigCorvus/ColorMemLCD
Arduino library for the LPM013M126A 176x176 Japan Display Color memory LCD found inside the SMA-Q2 / SMA-TIME smartwatch.
BigCorvus/SMA-Q2-Arduino
Arduino test firmware for the SMA-Q2 Smartwatch
BigCorvus/nrf52840-breakout
nrf52840 breakout board
BigCorvus/BL6280
The BL6280 is a controller for capacitive touch screens usually found on dirt-cheap chinese U80 "Smartwatches".
BigCorvus/nRF52832-Breakout
breakout board for the CDSENET E73-2G4M04S1B module
BigCorvus/Sharp-Memory-Display-Breakout
Breakout for the AYF531035A 10pin 0.5mm pitch connector which mates with the Shar Memory Displays and also the good old LPM013M126A
BigCorvus/SMA-Q2-Firmware-2
SMA-Q2 Firmware 2 based on the Sandeep Mistry Arduino Core or its Implementation in Aaron Christophel's portable Arduino IDE as uploaded here: https://www.youtube.com/redirect?redir_token=KBI_47xkebyV8zz_y1ZDXYYTUBF8MTU2OTA3MDI3N0AxNTY4OTgzODc3&event=video_description&v=3gjmEdEDJ5A&q=http%3A%2F%2Fatcnetz.de%2Fdownloads%2FD6Arduino.rar

BigCorvus/TPS63001-Minimodule
Small breakout for the TPS63001 - a 1.8-5.5V in and 3.3V out buck boost converter by TI
BigCorvus/Adafruit-ST7735-Library
This is a library for the Adafruit 1.8" SPI display http://www.adafruit.com/products/358 and http://www.adafruit.com/products/618
BigCorvus/Adalogger-with-TPS63001
The SAMD21-based feather adalogger with a different voltage regulator. It uses a TPS63001 synchronous buck boost chip to be able to use LiFePO4 batteries and still have a steady 3.3v. Another advantage is that more capacity can be squeezed out of LiPos, still maintaining a stable 3.3V rail.
BigCorvus/ArduinoZeroBluetoothHIDStick
Yet another keystroke injector based on the Arduino Zero/Feather M0 and the HC-05 Bluetooth module
BigCorvus/E-paper-breakout
A small universal e-paper breakout board for 24pin FPC EPD modules based on a standard schematic. Includes casellations for easy integration and a high side switch for complete power disconnect otion.
BigCorvus/ESP32-PICO-D4-Eagle-Library
nice ESP32-PICO-D4 Eagle Library
BigCorvus/Lithium-charger-and-LDO
This is a circuit that is used very often. It features a MCP73831 lithium charging IC capable of charging currents up to 500mA and a generic SOT23-5 LDO. I chose ultra low quiescent current mudels such as XC6215 in the 3.3V variant so the circuit can provide 3.3V all the time and last for ages
BigCorvus/NeuroWing
Feather wing that carries a 2ch bioamplifier board, a HC-05 bluetooth 2 module and some nice little features.
BigCorvus/PowerManager
Small power manager PCB based on a previously designed charger+LDO board. This new version has additional features: MCU-controlled power latching using a pushbutton and a fuel gauge with current sensing capability
