README
README.mdV1.0 -> First tentative version with following features:
made with Kicad, 2 layers, lots of vias :D
- battery monitoring
- battery charge/discharge maintanance LIPO
- buck boost regulator TPS
- Source selector that can select between mcu_bat or +12V automatically
- An RTC that can keep time even without battery. helpful for critical memory and notifications.
- An optional IO expander (PCF) providing 8 extra GPIO. can be left unpopulated. pcb should work fine.
- MCU used is ESP32 with bluetooth and wifi hopefully both being utillized
- Heater and egg turner both AC, egg turner is the continous type and is the only type currently supported.
- Main Voltage being used is +12V provided by jack, that will power fans, logic board. incase of power outage heavy stuff will be turned off automatically and it will go into power saving mode.
- Outputs (All 12V)
- Fan Exhaust
- Fan Continous
- Mist Maker
- LED lights
- Buzzer
- Water Pump
- Sensors/Inputs
- Water level sensor
- Display (I2C)
- Rotary encoder for menu (left, right and click)
- Temperature sensor (1 wire or digital)
- Temperature sensor #2 (1 wire or digital)
- Indicators
- Fault led, will light up if something is wrong according to code
- Busy led, will turn on when turning eggs or saving to memory
- Con led, shows connectivity of wifi, if connected will light up
- IO led, custom function or initial testing.
- Main power indicator led that will light up when 12V is connected through barrel jack.
This is how it looks as of right now.
PCB
Version 2
Better placement, hopefully this is better.
AC in one end and sensitive logic on the other.
