Oak Growth Applied sciences has unveiled one other board constructed round Raspberry Pi’s extremely well-liked RP2040 microcontroller: the compact, castellated, surface-mountable Forged-Away RP2040.
“Forged your venture fears away with the Forged-Away RP2040, a small and straightforward to make use of RP2040 dev board designed to take your venture to the seashore,” writes Oak’s Seth Kerr of his newest board design. “This board makes use of the favored Raspberry Pi RP2040, a dual-core Arm Cortex-M0+ microcontroller.”

The core of the Forged-Away RP2040 is, as Kerr notes, the Raspberry Pi RP2040 – the identical microcontroller, the primary product of Raspberry Pi’s in-house application-specific built-in circuit (ASIC) design time, as drives the Raspberry Pi Pico. As with the Raspberry Pi Pico there’s 2MB of off-chip flash reminiscence alongside 264kB of static RAM (SRAM) on the microcontroller.
To this, Kerr has added a USB Sort-C connector — an improve on the micro-USB discovered on the Raspberry Pi Pico — and a NeoPixel-compatible SK6812mini addressable RGB (aRGB) LED. There are bodily boot and reset buttons positioned on the corners of the board, and the design has elements on the highest facet solely — making it appropriate, together with the castellated GPIO headers, for floor mounting.
The Forged-Away RP2040 consists of 15 GPIO pins, however six are inaccessible in the event you’re utilizing a breadboard. (?: Oak Growth Applied sciences)
Given its significantly smaller dimensions, although, the Forged-Away RP2040 cannot match the bigger Raspberry Pi Pico for connectivity: 15 of the RP2040’s GPIO pins are introduced out to bodily headers, together with three analog pins, however solely 9 of those are accessible when the board is mounted on a breadboard. The three.3V pin affords 500mA output for driving exterior gadgets, and there is help for drawing as much as 3A at 5.5V from the VUSB pin when paired with an acceptable USB Sort-C energy provide.
Kerr has launched Eagle design recordsdata for the board beneath the permissive MIT license on his GitHub repository, whereas pre-assembled boards have been listed on the Oak Growth Applied sciences Tindie retailer at $5.50 — however, on the time of writing, had been listed as out-of-stock.
