2×2 Quad Display Board uses Raspberry Pi Pico W or ESP32-S3-WROOM-1 module to drive four displays (Crowdfunding)

SB Components’ 2×2 Quad Display Board is an MCU development board fitted with either a Raspberry Pi Pico W board or an ESP32-S3-WROOM-1 module used to drive four small color displays in square or round shapes.

The board specifically features either four 1.54-inch square TFT displays or four 1.28-inch round displays, a microSD card, an RTC with coin-cell battery holder, and a USB-C port for power and programming, plus a few buttons. It may feel like it’s coming out of the but-why-because-we-can department, but the company expects it to be used for signage, interactive displays, art projects, portable devices, data loggers, education, and more.

It seems to be a variant of the company’s Dual Roundy and Dual Squary displays introduced last January, but they upped the ante with four displays on the same side of the board.  Some may claim you could just achieve the same result with a larger display, although I reckon the 2×2 Quad Display Board may look neater than the alternative once it’s housed in an enclosure.

As usual, SB Components will not provide any code samples or deep technical details while the crowdfunding is in progress, and they usually release the software part before shipping the rewards, so MicroPython, CircuitPython, and Arduino samples should become available in due time. In the meantime, we can have a look at some of the demos in the video embedded below.

SB Components has launched the 2×2 Quad Display boards on Kickstarter with a 500 GBP target (620 USD). Rewards start at $57 US for the ESP32-S3 variants of the 2×2 Quad Display board, and $63 for the Raspberry Pi Pico models. Shipping adds 7 GBP to the UK, and about $19 to the rest of the world. As a comparison, an ESP32 board with a 3.5-inch touchscreen display like the Elecrow ESP32 3.5-inch HMI display costs around $20 plus shipping bearing in mind it lacks some of the features of the SB Components board. The 2×2 Quad Display boards are schedule to ship in June 2023 if everything goes according to plans…
