## Description

This is a **probe** for **ESP32 WROOM** module to use in conjonction with ESP-Prog JTAG board

* Lets you flash and debug an ESP32 controller that is already soldered into the PCB.
* Lets you flash  an ESP32 controller board that doesn't have embedded Programming port
* Lets you debug an ESP32 controller board that doesn't have embedded JTAG port
* Due to the use of magnets, it snaps together with the ESP and allows hands-free development.
* No need for tedious soldering to flash or debug the processor.
* You  also can use it for probing or connecting to the oscilloscope or logic analyzer.
* Precise ESP32 WROOM form cutout ensures a snug fit onto the ESP.
* It can be used for automated testing.
The ESP32 Flasher is designed to be used with one of the most popular ESP32 WiFi modules. 
The purpose of this tool is to make programming and debugging a lot easier, even in conditions where the ESP32 is already embedded into the PCB.

The thing is designed to be used without any additional wires. 
It uses spring-loaded (pogo) pins to make electrical connections to the ESP32 pads. This feature allows you to connect directly to the ESP32 that is already soldered to the PCB. 
The probe body holds magnets that keep the flasher conveniently connected to the module. Spring-loaded pogo pins (type R50) ensure electrical continuity even if the tool is not situated perfectly. 
Finally, two  2.54mm pitch IDC header  (PROG and JTAG) exposes  the ESP32 pins for easy debugging.

From now on, uploading the code, debugging, and testing pin states without soldering or designing any additional connections is possible. 
Last but not least, the clever use of magnets also puts you in a position to use the flasher while nicely snapped together with the ESP32.

**Please note :** Not all ESP32 units are made with a magnetic housing. In these cases, the flasher will function properly, but slight pressure will be needed to ensure that pogo pins make electrical contact with the ESP32 pads. 
This pressure can be easily maintained by hand or a type of plastic clamping device.

**What is included :**
The probe only
