It is a screw terminal breakout and prototype for TinyPICO ESP32 boards. Each pin of the TinyPICO is broken out to its own screw terminal, plus there are some additional screw terminals for power and ones that are user configurable.
I think I'm allergic to soldering wires anymore! I made a version of this board for the D1 Mini ESP8266 and I really like it, so I decided to make one for the TinyPICO.
I don't believe anything like this exists for any ESP32 based boards. I think it's the fastest way of building semi-permanent prototype projects. Did I just make up the term "semi-permanent prototype"? Maybe, but it sounds good!
It has the following features:
All 20 pins of the TinyPICO out to screw terminals.
Extra screw terminals for 5V and Ground, you can never have enough!
6 additional screw terminals connected to pads near the prototype area, these can be used for custom input or outputs to the project (e.g. if the output of a pin needs to go through a transistor/mosfet)
Prototype area with all GPIO pins broken out beside it for convenience.
Flexible power options - projects can be either powered from the 2.1mm DC jack (5V only, but useful for projects with larger current demands, such as neopixels), The TinyPICO USB port or via the 5V screw terminals
NOTE: Does not include a TinyPICO!
The PCB is 5cm x 8cm.
One thing to be careful about is that the TinyPICO does not have a USB back-feed diode. This would usually prevent an external 5V source being fed back up the USB cable. If you are powering the shield from an external 5V source, when you are programming the TinyPICO it may be safest to keep the USB and external power separate. Some ways you could do this: - Disconnect the external power while USB is connected - Remove the jumper block that is between the TinyPICO and barrel jack - Use a Power BloughR!
When the jumper is on the left two pins, the diode will be bypassed so the micro USB power will be connected to all the 5V pins.
