🖨️ ePaper displays are ultra-low power and sunlight-readable, but come with slow refresh rates, limited colors and relatively high prices. Perfect for digital signage, electronic labels and eReaders.
🎥 In my spare time I created a video tutorial to explore using the same 4.2" monochrome ePaper (400×300, SSD1680, SPI) display with two different controllers: the @seeedstudio EE04 with XIAO ESP32-S3 and the ePaper Breakout Board with XIAO ESP32-C3.

🚀 XIAO ESP32-C5 is the first @seeedstudio XIAO module with dual band WiFi 6, supporting both 5 GHz and 2.4 GHz. It is a game changer for DIY IoT!
⚙️ It features a 32-bit RISC V MCU running up to 240 MHz, along with 8MB Flash and 8MB PSRAM.
🔗 Connectivity options also include Bluetooth 5 LE, and Zigbee and Thread support for Matter.
🎥 I created a beginner friendly video that shows how to get started with XIAO ESP32-C5 in the Arduino ecosystem:

Trying out my new setup with Ducky One 3 TKL #mechanicalkeyboard with hot-swappable Cherry MX red switches.
I upgraded the main keyboard from 60% Ducky One 2 to TKL and from silver to red switches.
