You can now buy Raspberry Pi RP2350 MCU for 80 cents and up, RP2354A and RP2354B variants coming soon

The Raspberry Pi RP2350 dual-core Cortex-M33/RISC-V MCU was first unveiled along with the Raspberry Pi Pico 2 in August 2024. Since then we have covered many Raspberry Pi RP2350 news and boards, but the microcontroller was hard to source for hobbyist and low-volume projects, which partially explains why companies like NextPCB had promotions offering free PCBA prototyping services for RP2350 designs. The good news is that Raspberry Pi has just announced general availability for the RP2350 microcontrollers starting at $0.80 per unit for the RP2350A in 3,400-piece reels, or $1.1 in single quantity, so anybody can buy the MCUs from their favorite distributor. The British company also announced the RP2354A and RP2354B variants with 2MB of stacked flash memory would soon be available to select partners and mass production will ramp up later this year. Here’s the current official pricing information for the RP2040 and RP2350 microcontrollers. Users can simply […]

FlashMyPico – Raspberry Pi Pico / Pico 2 code editing and firmware flashing from a web browser

FlashMyPico website allows you to write C code, build the firmware, and flash it to your Raspberry Pi Pico, Pico W, Pico 2, or Pico 2 W directly from a web browser instead of having to check out the code from GitHub, build it in a terminal, and then manually copy the resulting binary. I’ve given it a quick with a Raspberry Pi Pico 2 board. The first step is to head over to flashmypico.com from your computer or even an Android smartphone. You’ll need a web browser that supports WebUSB, so for example, Firefox is not an option, and I eventually had to use Google Chrome instead. There’s a detect device link on the bottom left, so I clicked on that first, and my Raspberry Pi Pico 2 was detected as “RP2350 Boot” after I put it in bootloader mode. But it just told me that my board is […]
