Adafruit is making ready to launch a Raspberry Pi RP2350 Feather-format improvement board with an fascinating further characteristic: a flat versatile circuit (FFC) connector at one finish to offer entry to the microcontroller’s high-speed transmission (HSTX) port.
“[The] RP2350 flies excessive with the Feather format — now you should use any FeatherWings with this battery-powered dev board,” Adafruit says of its newest {hardware} design. “It comes with 8MB of flash, 22-pin HSTX output port, STEMMA QT, debug SWD [Serial Wire Debug], and optionally available PSRAM [Pseudo-Static RAM] spot. It is our first RP2350 board and we crammed a ton of goodies into our basic Feather format. It is a superb starter board to go together with your Pico 2.”

The Raspberry Pi RP2350 was unveiled, alongside the Raspberry Pi Pico 2, early final month as a follow-up to the favored RP2040. Nonetheless designed in-house by Raspberry Pi’s chip crew, the RP2350 boasts each Arm Cortex-M33 and open-source Hazard3 RISC-V cores, expanded Programmable Enter/Output (PIO) blocks, practically twice the reminiscence, and assist for exterior PSRAM the place required.
It additionally has one thing lacking from the RP2040: a high-speed transmission (HSTX) peripheral. This, because the identify implies, supplies a method to transmit information at a excessive price with out tying up the PIO blocks or a CPU core — offering a straightforward approach to drive a digital show, amongst different potential use-cases. Adafruit’s Feather RP2350 brings this out to a 22-pin FFC connector at one finish, making it simple to entry — whereas additionally bringing out different general-purpose enter/output (GPIO) pins, together with 4 analog pins, to breadboard-friendly headers pin-compatible with different Feather boards.

Elsewhere on the board are a user-addressable pink LED and an RGB led, a STEMMA QT connector for solderless growth, a JST SH Serial Wire Debug header appropriate with the Raspberry Pi Debug Probe, and a 200mA charging circuit for an optionally available lithium-polymer battery. There’s 8MB of flash, and a footprint for an optionally available PSRAM chip — although, on the time of writing, Adafruit had not but introduced a model with this populated.
The Adafruit Feather RP2350 with HSTX Port is listed on the official retailer at $12.50, although on the time of writing was displaying as out-of-stock; purchasers are suggested that, like all different RP2350 boards, it is affected by erratum RP2350-E9, and would require robust exterior pull-down resistors owing to a {hardware} flaw affecting the interior pull-downs.
