Yet another new ESP32 development board

New ESP32 Development Board!

Well, this is not much of a surprise. This new ESP32 development board comes with standard DIP size, breadboard friendly header for easy prototyping. The ESP31b had a similar development board out, in a similar form factor and specifications.

This ESP32 development board seems to have the ESP-WROOM-32 module, just like the ESP32 demo board. There is a slight difference in the USB-to-UART bridge part. This chip used here is the CP210x, not the FT232. Not that it makes much of a difference. We wonder if this ESP-WROOM-32 version supports JTAG debugging? Certainly no mention of that on the header pins.

We enhanced the image a little so that the details are clearer. There seems to be no Espressif logo on the board on the top side. It might be that the board is not a production run one.

ESP32 Board Highlights

There are some features/specs that can be immediately noted about the board:

  • ESP-WROOM-32 module without shielding can
  • Almost all GPIOs accessible
  • MicroUSB connector for power
  • Two buttons – BOOT and EN
  • On-board 3.3V regulator
  • CP210x USB-UAR bridge
  • And a chunky diode? What is that for? Comment your guesses!

Apart from this, a closer inspection reveals some serious amount of flux residue on the solder joints. The header will be hand soldered, that is expected. But here the ESP32 module itself seems hand soldered. So it might be that the board is not a production run one – more like a hand-assembled one for initial evaluation.

Which points to the fact that it will take a while before we see ESP32 hit the market and be readily available for purchase.
