The USB ESP32 WROOM programmer can flash ESP-WROOM-32 modules in circuit without having to desolder them first. It features 37 pointy pogo pins to be directly pressed onto the ESP.

You can connect a USB C cable (not included) to it and use Arduino IDE, PlatformIO or others to upload code. It features a RESET circuit similar to nodeMCU so you can upload without having to press a button. IO0 and RESET are still routed to buttons, so the ESP can quickly be reset or put into programming mode manually if needed.

The USB to serial converter is a CH340, which works natively in the Arduino IDE on Windows, Mac and Linux. The seven most relevant pins (EN, IO0, 5V, 3V3, RX, TX, GND) are broken out and labeled in case you want to use it for something else. Rx and Tx have LEDs on the CH340 for quick feedback. There is a power LED and a LED for IO0. The setting used in the IDE confirmed to be working for me are Board: "ESP32 Dev Module" and Upload Speed: "115200"

It can also probably flash ESP32-WROOM-32SE, ESP32-WROOM-32E, ESP32-WROOM-32D, ESP32-SOLO-1 and most certainly all others that have the same pinout and spacing.

The board has all ESP32 pins as pogo pins to be easily connected with the standard 2.54mm (0.1in) headers. Those are not supplied by default, but can easily be added. It has an 3.3V regulator on board which can directly supply the ESP.

The Kit includes extra pogo pins and an instruction on what to solder where. You will need a soldering iron and accessories to solder it together. Please note that you have to have quite a steady hand to solder the pins yourself. They can not be bent and like to wiggle out of the way. The board may have a different colour depending on the standard option from the board house.

The Fully Assembled Version comes as pictured and can be directly used to play around with it. Please note that most of the additional charge is because of the tricky shipping of the pointy pogo pins.

The ESP is not included ;)
