HiLetgo ESP32-WROVER Development Board Programmer Tool Burning Fixture Tool Test Socket Downloader for ESP32-WROVER ESP32

I bought this to program some ESP-12F development boards. Only hiccup was finding the drivers to install. Once the drivers were installed, programming these was a piece of cake.

I've been using this to program various 8266 chips, and it works great.

Very hard to tell if the board even works since the pins were so poorly aligned that I couldn't get my chip to sit properly connected in either, even after many attempts.

This board, as I recived it, did not work correctly in so far as ESPTool could not reliably put the device into boot mode for programming. This is due to an under-sized capacitor on the reset/EN pin. Adding a 1uf capacitor from EN to GND seems to fix the problem. Otherwise 5* for a really useful tool. Hope this helps anyone else who's about to throw the thing in the bin.
