Expanding the XIAO Ecosystem: New ePaper Driver, Relay, Power, and Sensor Add-on Modules Released
We’re introducing 4 new add-on modules for Seeed Studio XIAO, including a new relay, an ePaper Driver Board, an expansion board with power supply and meter, and a sensor – all compatible with Seeed Studio XIAO boards!
We’ve heard from our community about the limited number of compatible add-on modules for our tiny but powerful Seeed Studio XIAO boards. Starting 2025, we’re addressing this by developing more XIAO add-ons!
Seeed Studio XIAO Add-ons are expansion boards, sensors, connectivity modules, and actuators with a socket where Seeed Studio XIAO dev boards (pre-soldered versions) clip right in. You can explore the full collection on our Seeed Studio XIAO Selector page.
For our first product collection of the year, we’re introducing a new relay, ePaper Driver Board, expansion board, and sensor – all compatible with Seeed Studio XIAO boards!
Compatibility: all Seeed Studio XIAO Pre-Soldered Dev Boards (SAMD21, RP2040, nRF52840, nRF52840 Sense, ESP32C3, ESP32S3, ESP32S3 Sense, ESP32C6, RP2350, RA4M1, The pre-soldered variants for XIAO MG24 and XIAO MG24 Sense will be coming soon)
This ePaper driver board features a 24-pin FPC connector, a built-in charging IC, and a JST 2-pin BAT connector. It’s perfect for creating WiFi-enabled digital photo frames, supporting various ePaper displays (2.13″ Monochrome eInk / ePaper Display with 122×250 Pixels, 2.9″ Quadruple Color eInk / ePaper Display with 128×296 Pixels, 5.83″ Monochrome eInk / ePaper Display with 648×480 Pixels, 2.9″ Monochrome eInk / ePaper Display with 296×128 Pixels).
Compared to our 2023 ePaper Breakout Board, this new version includes:
- JST 2-pin BAT connector
- Built-in charging IC
- Onboard power switch
- Extra 14 IO pins for expansion
- Standard XIAO add-on dimension (which is the triple size of a XIAO board)
Don’t worry – we’ll keep both versions available to suit different application needs. Currently, this new ePaper Driver Board is available for pre-order at $4.9, with estimated shipping at the end of January 2025.
