Got our ESP32-S2 Feather PCBs in last night, so now we’re putting them together and trying it out. These Mini modules are the perfect size but don’t come with PSRAM so we have to freeze in some CircuitPython modules to make everything fit (the WiFi stack + SSL requires a lot of RAM which is where most of it goes). However, once we did that we whipped up a demo that takes data from the onboard BME280 and battery monitor and sends them over the wifi to adafruit.io for plotting. It just fits into RAM and works a treat. Next up we’ll try out the same code in Arduino – 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.

Hey folks, I was wondering if you would consider breaking out the jtag pins on the esp32-s2 when you make this board? 39, 40, 41, 42.
Maybe just to some test-probe points which should be pretty cheap to do before the boards are finalized.
