ESP-07S (ESP8266) programmer

thingiverse

Programming fixture for ESP-07S modules. Requires: 16 pins from sacrificed PCI connector (KORTAK). 1 pcs. Wemos D1 mini board. Remove the ESP module from the Wemos board (use heat gun). Pull 16 pins from the PCI connector (goes easily out from the bottom side). Only use pins from the two inner lines. Mount the pins in the printed inner part from the bottom side. You need to compress the spring a little while pushing the pin into the bottom slot. When all pins are mounted in the inner part, clean the Wemos board and glue the printed inner part to the Wemos board. I used Loctite Super Glue Precision. Assemble the fixture to align the Wemos board and the inner part while the glue is hardening. When the glue has hardened, disassemble the fixture and solder the pins to the Wemos board pads. Take care not to apply too much heat as the PLA easily melts. The ESP-07S module will click into the fixture and will sit firmly during the programming operation.
