The project started as a learning exrecice to make a tiny some what low power esp32. The MCU thet was selected for it was the ESP32-C3FH4 with 4MB of built in flash and a total of 22 GPIO pins. More info about components are under each versions directrory since most componens differ.
- max size 1" x 0.75"
- < 500 mA peak
- < 5 mA deep sleep
- External antenna (U.Fl connector)
- USB-C (For flashing and powering.)
- 1s li-ion or lipo powered
- GPIO
- min 4 Digital
- SPI
- I2C (IIC)
- min 2 Analog
- min 4 Digital
Some later goals are:
- max size 0.9" x 0.5" x 0.5"
- power LED (3.3v)
- lipo charging (Via USB-C.)
