Metro ESP32-S2 is so close to release! Tester time…
A Raspberry Pi with PiTFT makes for a perfect ESP32 tester/programmer, we just have it run esptool and program in a self-test sketch to the ESP32, then read the output from over the USB serial connection.
The self test checks all the pins are connected properly – not floating, not shorted – as well as the power supply voltages and battery charger functionality. Then once it passes test we program in CircuitPython 6! – video.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
