### CHPC: Cheap Heat Pump Controller v1.0 ## Development State: active Discussion: https://www.forumhouse.ru/threads/469103/ ## PCB Design There are 2 PCB designs: type "F" and type "G". Both untested. ## Type "F" features: - **mostly SMD** componens, - **internal power** source, - **10** output channels, - 5 output channels, - 4 input channels, - 5 relays: 1 * 16A + 4 * 7A, - buzzer, - EEV support, - 16 bit **i2c ADC: on board**, - i2c devices: allowed, - ds18b20 on one lane. ## Type "G" features: - **no SMD** components, - **external, board-placed** power source, - 5 output channels, - 4 input channels, - 5 relays: 2 * 16A + 3 * 7A, - buzzer, - EEV support, - 16 bit **i2c ADC: off board**, - i2c devices: allowed, - ds18b20 on one lane. # Type "F" PCB  # Type "G" PCB
