Summary

After you print it out, you'll need to drill out the holes for the pogo pins and use hot glue to ensure that they do not short out on each other. Refer to this wiki for loading Tasmota onto the board https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-DIY. The jig will gently snap onto the board. Make sure that the pogo pins are properly lined up before powering on the FTDI.

Here's the parts list.

6 - P75-E2 Spring Test Probe Pogo Pin 1.3 mm Conical Head 1.0mm (I recommend having spares)Female Header 1x40 2.54mm (trimmed down for an easy connection from the FTDI to the pogo pins)-hot glue to hold the header/pogo pins in place

Backstory:

Starting with the Instructables post by Eric Tsai (https://twitter.com/Eric_1100). I found inspiration with DIY home automation. Computourist (https://github.com/computourist/RFM69-MQTT-client) cleaned up the programming and added the ability to transmit to end nodes. Then I found a great forum that has simplified the build and offers a great community http://homeautomation.proboards.com/post/2053/thread

This is my attempt to contribute back to the http://homeautomation.proboards.com/ community
