#Mosquitto board

This is a Kicad 7 project for the Mosquitto board.

Features:

• Based on the ESP8266 ESP-12F module
• On-board CP2102 usb-to-serial converter for programming and debugging
• USB Type-C connector for programming and power
• On-board SHT30 temperature and humidity sensor
• Header for a 3 pin screw-terminal for hooking up onewire sensors
• A pmod-i2c and pmod-spi header for attaching sensor breakout modules
• On-board battery charger for Li-ion or Li-Po cells (protected cells needed)
• Deep sleep timer circuitry included
• ADC pin is hooked up for low-power battery level monitoring
• Fabrication metadata for Aisler and JLCPCB assembly

Things that need fixing for the next revision:

• Fix the backfeed diodes between the ESP and the CP2102, these need to be bridged for programming now
• Add a battery protection chip
• Include an auto-reset circuit for programming
• Decouple the heat generated from the usb-serial chip from the on-board temperature sensor better
• Add a pin header for the serial port
• Figure out the annoying parts of the cern license
