rp2040 based microcontroller
Budget: $200 – $400 USD
The board will have 2 main functions. First, 4 gpios will be used to send PWM signals to a 4in1 ESC to control 4 brushless motors. (Wired control thru an ADC pin set) A tri-state 4 channel bus converter will be needed for outputting 5V PWM ( something like 74ahct125 ). Second function will be controlling a linear solenoid with onboard MOSFET and diode.(Solenoid power consumption Vout<20V, C~30A) The solenoid cycling speed/frequency will be controlled by a second pin set of ADC. 2 additional switch pin header will also be required to act as on/off to each circuit. Plus A USB C port alone with a reset and boot button. I want the PCB to be as small as possible. Less than 25x25mm/30x30mm.
P.S. I want to have direct solderable pads on the board for Vin,GND and Vout GND for the solenoid part. I attached a vague reference of PCB design, that’s my knowledge limitations
