Drive LED strips or any high current ~6A devices with this power board. Developed by Rob from the 43oh Forums. This is the PCB only, unassembled. This is a standalone version of his MOSFET BoosterPack.

Details

• 20 or 14 pin DIP to hold MSP430G series chip
• TO-220 LDO/regulator
• Programming header
• GPIO headers Up to 2 additional boards can be attached for a total of 8 or 12 channels
   

BOM:

• IC1 - MSP430G2553IN20 PDIP (other G series chips will work too, but you may loose some functionality.)
• IC2 - 3.3V TO220 LDO
• Q1-Q4 - IRLB8721 TO220 MOSFET
• LED1-LED4 - any 3mm or 5mm LED
• D1-D4 - 1N4004, 1N5818 (or similar)
• R1-R4 - 100ohm, gate resistor (47-220 can be used)
• R5-R8 - 100k, gate pull-down resistor (10k-100k can be used)
• R9 - 47k
• R10-R14 - same as R1-R4, but only 4 are required, see schematic
• 5mm terminal blocks
• C1 - 47uF-100uF/6.3V-10V
• C2 - 10uF-100uF/10V-25V (depends on input voltage.)
• C3 - 0.1uF
• C4 - 1nF

Use Cases

• Dumb RGB strip driver
• Relay/motor driver
• Incandescent light driver
