Flashing jig

The flashing jig

The jig holds one label at a time with pogo pins on its debug pads, so you do not have to hold the pins. It is a 5 × 7 cm perfboard with a Wemos D1 mini running atc1441's ZBS_Flasher, and three 3D-printed parts.

Parts

• Wemos D1 mini (ESP8266)
• 5 × 7 cm perfboard
• Pin headers for the D1 mini (2 × 8)
• Pogo pins, one per hole in the upper part
• Wire, and a USB cable for the D1 mini
• The three printed parts (bottom, upper, insert)

Building it

1. Build the flasher: a D1 mini with ZBS_Flasher, a small power switch and the wires to the pogo pins. Building the flasher has the parts, the wiring, the ZBS_Flasher settings and how to test it.
2. Print the three parts and put the pogo pins in the upper part.

Other flashers

ZBS_Flasher also runs on an ESP32 or an Arduino Nano, and on most boards with about eight free pins and a serial port. OpenESL is tested with the D1 mini. If you use something else, tell us.
