This is the casing for the Wemos D1 Mini (custom shield) ARDPM+ (PIN Extender) .
This D1M BLOCK adds an additional 16 digital pins and 4 analog pins via I2C (only using 2 reusable I2C pins). This is an integrated extender (extra pins and breakouts combined) and exposes the 2 main rows of the Arduino Pro Mini. The initial footprint of the D1M BLOCKS is preserved and the Pro Mini is powered from the breakout pins.
These components, a SOCKET JIG for soldering, and 2 off 8 pin 10mm Long Needle Female Pin Header Strip are required for this build.
Align large, non-beveled surface to bed.
