IOT123 - D1M BLOCKS

About: The tension between novelty and familiarity...

D1M BLOCKS add tactile cases, labels, polarity guides and breakouts for the popular Wemos D1 Mini SOC/Shields/Clones.

This Instructable is instructions for the instructions; it indexes all the different projects and points to where the articles and resources are for each project.

Step 1: D1M WIFI BLOCK

A mini wifi board with 4MB flash based on ESP-8266EX.

Step 2: D1M BLOCK INSTALL JIGS

These jigs are used to set the headers at the correct offset to get maximum pin penetration when using the D1M BLOCK casings. Two of the jigs are used for soldering and one is used during gluing (base and lid glue).

Step 3: D1M 18650 BLOCK

This is a fairly specialized piece and is seen as a starting point for more flexible designs. It breaks out the 18650 +3.7V (to 5V on D1M BLOCK) and GND (to GND). The 5V pin on the Wemos D1 Mini is connected to a regulator that drops the voltage to 3V3 for that pin on the D1 Mini. This design also supplies brackets for mounting the power supply on a bike helmet.

As with all the D1M BLOCK's, the pins and offsets are built for easy stacking of multi-block circuits.

Step 26: D1M ACAM2 BLOCK

This D1M BLOCK encapsulates and breaks-out the ArduCam 2MP camera (OV2640). This component can take stills and video, persisting to the web, to your ESP8266 webserver or SD Card. A lens cap is included (mine did not come with one).

Step 27: D1M ARDPM+ BLOCK

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.
