Test Burn Board Small Batch Burn Fixture for ESP-WROOM-32 Minimum System Development Module wled Controller esp32 wt32-eth01 esp32 Programmer

I had no problems using this product in my Mac. The pins for the chip are sturdy and provide a good grip. The extra pins are very handy for plugging external peripherals for testing.

I opened the package up only to find that two of the screws that hold the PCB to the backer are missing. Upon further investigating, it appears the screws came out prior to packaging as the holes will not fit a screw in due to being too large. Not only that, but most of the header pins are bent and the MCU spring pings are also bent and contacting. Normally I would send this back, and probably should do so, but it does not prohibit the function of the product to just burn some MCUs.

The pins that hold the chip down are just springy wires, they work well enough and require minimal force to insert and remove. I've used a few WROOM-32 modules with this product and it seems it will last for a while under moderate usage. I guess I'll update after the unit ceases to function. The micro switch included as the Programing button is standard but would work so much better if it were a toggle instead of a momentary switch. This product is really small 50cmX50cm.

The media could not be loaded.  It seems this device was hand made and badly at that. Contacts are not straight, soldering is unprofessional and messy and Flux all over the board, which I had to clean. A piece of paper is still glued to the board!

The board is well constructed. The pins that connect to the ESP32 are springy and stiff enough. After loading the SILAB driver on my host computer, I was able to easily flash the ESP32 with micropython.

What is shown in the description is for an ESP32-WROOM. That is what I wanted. Instead, what I got was for the ESP32-WROVER. This happened twice. Not happy!

Nice
