QT Py with ESP32-S3

Front

Back

just one more pcb design and then we promise we’ll stop (naw, we will never stop) this is a swap-out of the ESP32-S2 QT Py for the new ESP32-S3 chip. The S3 is really a nice piece of kit – dual core is back and it also re-adds BLE. It’s basically an ESP32 with native USB, we’re looking forward to it! note that the S3 chip looks a lot like the S2 but the chip pinout is NOT the same, the reset, and some power pins have moved. and some gpio shifted down one. also, looks like the dual DAC was removed. anyways, just watch out don’t think you can use the exact same layout. we had to shift a few parts but it all still looks like it fits! top part is identical to the S2 QT Py, and the bottom only shifted a few passives around. we’ll get some 4 layer prototypes on order. #comingsoon


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.
