Total Price:
$38.45
FeatherWing for Adafruit Feathers to control two relays via I2C using an MCP23008. Component selection based on the Adafruit Power Relay FeatherWing, but modified to use through-hole components and the MCP23008.
Requires 5V in.
I recommend getting this printed using the 2oz Copper with 0.8mm FR4 option
For the Feather I have test this with and used the Adafruit Huzzah 8266, but any Feather should work.
BOM:
- P1: Traco TSR-1 2433
- U1: MCP23008
- R1, R3, R4, R6: 1KOhm Resistor 1/4W
- R2, R5: 10KOhm Resistor 1/4W
- R7-R8 - 4.7KOhm Resistor 1/4W
- D1-D2: 1N4148
- J1: PJ-102A
- K1-K2: G5LE-14 DC3
- T1-T2: 5.08MM 3 pin screw terminals. I got mine from Amazon.
- Q1-Q2: PN2222
