SB Elements is crowdfunding for a brand new pair of good embedded show boards, obtainable in spherical or sq. codecs and boasting, unusually, a show on each side: the Duo Show Twin Squary or Twin Roundy.
The Duo Show fashions construct, as their names suggest, on SB Elements’ present Squary and Roundy good shows — the previous obtainable because the SquaryPi and SquaryFi and utilizing a hard-edged show, whereas the sooner RoundyPi and RoundyFi used round shows. In each circumstances, the “Pi” and “Fi” suffix signifies the microcontroller sort on board: both a Raspberry Pi RP2040 or an Espressif ESP-12E with Wi-Fi connectivity, a cut up decisions which comply with by way of to the brand new fashions too.
“DuoPi options the RP2040, whereas DuoFi boasts the ESP32-S3-WROOM-1 microcontroller,” SB Elements Kamaluddin Khan explains of the brand new embedded show household, “offering customers the flexibleness to effortlessly swap between them, all wrapped in smooth interchangeable shows. [The displays are] a groundbreaking tech companion that gives a novel mix of versatility and creativity.”
This time round, although, there’s greater than a few decisions within the combine. The Twin Roundy and Twin Squary gadgets are constructed from two distinct PCBs, one among which hosts the microcontroller and one show with the opposite holding a second show and a microSD slot for native storage. Should you solely want one show, the 2 cut up in half — and you’ll take the second show from an RP2040-based board and use it with the ESP32 model, and vice-versa.

The round-display fashions use a 1.28″ colour panel with a 240×240 decision whereas the sq. variations go for a 1.53″ show with the identical decision — with neither supporting contact inputs. No matter show form or microcontroller, all fashions embody a six-degrees-of-freedom (6DoF) inertial measurement unit (IMU), user-programmable RGB LEDs, microSD storage, a USB Sort-C port for energy and information, and a battery connector. All fashions additionally embody no less than two user-definable push-button switches, with the sq. fashions having three.
The boards are actually funding on Kickstarter at £40 (round $51) for one controller board and one add-on show and microSD board, no matter form or microcontroller; a £45 (round $57) “tremendous early chicken” bundle provides each the ESP32 and RP2040 controller boards with one interchangeable add-on show and microSD board. All {hardware} is predicted to ship in Might this yr, SB Elements has confirmed.
