The Raspberry Pi Pico SDK 2.1.1  has just been released with official 200 MHz clock support for the Raspberry Pi RP2040 MCU, several new boards mostly from Waveshare, but also one from Sparkfun, as well as new code samples, and other small changes. Raspberry Pi RP2040 gets official 200 MHz clock support When the Raspberry Pi RP2040 was first released along with Raspberry Pi Pico in 2021, we were told the default frequency was 48 MHz, but the microcontroller could also run up to 133 MHz. Eventually, I think the Cortex-M0+ cores were clocked at 125 MHz by default, although some projects (e.g. PicoDVI) would boost the frequency up to 252 MHz. Frequencies higher than 133 Mhz were not officially supported so far, but the Pico SDK 2.1.1 changes that since the Raspberry Pi RP2040 has now been certified to run at a system clock of 200MHz when using a [...]

WeAct MSPM0G3507 is a BluePill-like development board equipped with Texas Instruments’ 80 MHz MSPM0G3507SRHBR Arm Cortex-M0+ mixed-signal MCU with 128KB flash and 32KB SRAM. The board features a USB-C port for power and programming, two buttons for Reset and BSL (Bootstrap Loader), a 4-pin SWD port for debugging, and two 18-pin headers for GPIOs, CAN Bus, ADC, DAC, I2C, UART, and other interfaces. The MSPM0G350x microcontroller also comes with a math accelerator for DIV, SQRT, MAC, and TRIG computations which could prove useful for control control and signal processing. WeAct MSPM0G3507 specifications: MCU – Texas Instruments MSPM0G3507 Arm Cortex-M0+ microcontroller at 80 MHz with 128KB flash, 32KB SRAM, 2x 4Msps ADC, DAC, 3x COMP, 2x OPA, CAN FD, MATHACL math accelerator USB – USB-C port for power and programming via CH340X USB to TTL chip Expansion – 2x 18-pin with power signals, I2C, SPI, GPIOs, ADC inputs, DAC, CAN Bus, [...]
