PCB with 4 channels mosfet power switches
Budget: $30 – $250 USD
Create a PCB with mosfet power switches for 4 lines (both positive and negative wires), controled by PWM signal (high is on). And current control circuit, to connect to external STM32 MCU.
Power in is single 5-13 volts power supply for all.
Max current for single line is 2 Amps. It will newer use more than one line at once.
LED indicators for:
Green - power in
4 pcs red ones for indicating a power at the output of each power line.
Also need to install connectors:
1x JST-SH1.0 7pin connector (Vin/G/Curr/S1/S2/S3/S4) - S1-4 is PWM to control mosfets.
Connector need to be installed on one edge of PCB, LED's on second edge, and soldering pads for power outputs on the opposite side to JST-SH connector.
Dimensions of PCB need to be:
Mounting: 30.5 x 30.5mm, Φ3mm.
Outer dimensions: 36 x 36.
Other requirements:
- no dip elements must be used.
- project must be in KiCad.
