I use a Raspberry PI for my home automation. Security, Heating, Cooling and Irrigation.
I use a mix-and-match of IO cards and relays. Wiring is a mess.
I looked for an compact IO card to do all I needed and could not find it, so I designed my own. I am thinking of trying to sell it.
The card is a stackable HAT, it passes through 23 GPIO's from Raspberry and it adds another 18 of it's own.
Twelve of the 18 GPIO's can be configured as 12 bit ADC's. It also has eight on board relays, eight optically isolated inputs and one DAC output.
Timers lurch in the dark, can be programmed if needed. STM processor on board with PWM and lots of other I/O resources.
Q1. What are the restrictions of using the Raspberry logo on HAT cards?
Q2. Anybody thinks this card is a good idea, or it's just in my head?
