We slept in and had a tasty bagel breakfast, then jumped into our first design of the year. Building off the two Feather ESP32-S2 PCBs from yesterday, we flipped the TFT onto the back and accessorized it with some tactile buttons. We’ve been trying to design a TFT+WiFi all-in-one Feather for a few years ago, since we started making PyPortals… almost two years ago we started designing a low cost ‘mini PyPortal’ that would be able to run CircuitPython. (kinda like those lilygo all-in-one esp32+display boards folks have been using for a few years, but we don’t have circuitpython running directly on the original esp32) We started with a Feather M4 and tried putting an ESP32 + OLED into a panel-mountable design we couldn’t fit everything without it being so large we couldn’t really count it as a Feather anymore. The improvements in mini TFT and module technology since then allows it to be reborn again!

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.
