Description
2 layer board of 1.80x1.60 inches (45.72x40.64 mm).
This board is a meta-breakout board for Pololu’s DRV8825 stepper driver module, designed to hold a custom-machined heatsink, capacitor, screw-terminal connectors, and an indicator LED for fault conditions.
C1 is a Panasonic H13 100µF 63V electrolytic capacitor (EEE-TK1J101AQ).
D1 is an 1206 red LED - OSRAM’s LH N974-KN-1
Q2 is a P-channel MOSFET - NXP BSS84,215. Q1 and R1 are non-existent.
R2 is an appropriately-sized 0805 current-limiting resistor for your choice of LED.
JP3 and JP4 are 2 and 4 position 3.5mm screw terminals. Phoenix 5452604 and TE 284391-2 work.
