Seeed Studio Round Touchscreen Display for Xiao / QT Py: Seeed Studio Round Display for XIAO is an expansion board compatible with all XIAO development boards. It features a fully covered touch screen on one side, designed as a 39mm disc. It contains an onboard RTC holder, charge chip, and MicroSD card slot within its compact size, perfect for interactive displays in smart homes, wearables, and more.
Adafruit Switchable USB Type A to C Breakout Board: We don’t quite know what to call this doohicky – some folks refer to it as a USB Condom but that’s specifically for when the data lines on a USB port are disabled so that a device charges without data access. This board is a little more advanced: you can manually switch each of the 4 wires on or off for a variety of uses.
Adafruit CH9328 UART to HID Keyboard Breakout: We love using chips with ‘native USB’ peripherals – that’s the magic silicon that lets a microcontroller act like an HID keyboard or mouse or disk drive or MIDI synth. It’s a standard addition on SAMD21, RP2040, and even the latest ESP32-S2 and ESP32-S3 boards. But what about when you have a classic ATmega328 Uno? or an original ESP32 or ESP8266? Maybe even a single-board computer like a Raspberry Pi? We would say “sorry…that’s not possible” UNTIL NOW!
The CH9328 is a funky chip that is basically a programmed microcontroller that enumerates as an every-day HID keyboard and can convert ASCII or 8-byte raw reports, read over a standard serial port UART, into keypresses. So, you can emulate a keyboard even if your chip doesn’t have native USB! You do need a hardware or software serial port: some way to generate 9600 baud 3V-logic signal that the CH9328 can read.
