What is it?

The Ultimate ESP32 Development Kit, Includes adapters for 30 Pins, 38 Pins and Breadboard!

Why did you make it?

The ESP32 DevKit V1 and DevKitC are very popular with hobbyists and professional IoT projects, When I've started to work on them in a more professional capacity, I've found out I'm missing JTAG and using them on breadboard is not enjoyable as it could be due to their size.

Why not make a generic adapter and instead of repeatedly connecting and disconnecting. Just use the same host with multiple adapters!

What makes it special?

Its unique amongst its friends, There are no commercially available DevKits form factor available with JTAG and having the ability to disconnect the host and reconnect it to multiple other adapters during development saves a lot of time and broken pins.

Whats included?

• ESP32 Host with 10/20 Pins JTAG IDC connectors, 40 Pins header and Micro SD Card Socket.
• Breadboard adapter - includes headers, leds, jumpers. breadboard not included.
• 30 Pin Adapter - includes headers and 40 pin IDC.
• 38 Pin Adapter - includes headers and 40 pin IDC.
• 40 Pins flat cable 20CM long

Note: Requires Soldering!

Connections

• Micro SD CS=13, DI=15, CLK=14, DO=2
• JTAG TDO=15, RST=EN, TMS=14, TDI=12, TCK=13

Micro SD and JTAG CANNOT BE USED TOGETHER!

This Kit does not include 38 Pin ESP32 DevKit. Fits 25mm and 23mm wide DevKits, measure before you solder!

Example Uses:

• Prototyping - use the breadboard adapter, its narrow and leaves 4 places on each pin to connect modules and components as well as dual voltage (3.3v/5v) power rail distribution, when you're done, you don't need to disconnect the ESP32 from the breadboard, just disconnect the cable and use as standalone or on a different project, purchase multiple kits if you have many breadboards to quickly try different designs or find differences.
• Debugging - the host comes with JTAG connectors you can debug on your prototype, if you experience issues its very easy to disconnect a cable than to pry out components to figure out the problem, easily diagnose problems with the annoying GPIO12 issue.
• Debug a working prototype by using the 30/38 Pins adapters, just connect the host and guest and debug away!
• Contemplating Micro SD card use for your project? the Host comes with Micro SD slot connected to the default HSPI pins!
