We are noodling through some old designs we did not finish routing. There’s still some ground plane work to do here, but all the pins are routed and assigned…somehow our designs always use *all* available GPIO, nothing left over! The ESP32 adds WiFi and BLE through an SPI interface, with TLS 1.2 and all so IoT projects are possible. Only thing that is a bit odd is that D0 and D1 are swapped so that the UART direction is ‘correct’ with the pinmux. or at least, we think so? UARTs are always tricky to wire up… #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.
