KEHIPI

KEHIPI Raspberry Pi Pico 2 Pre-Soldered Header Development Board

SKU CH-7TGF-8BT9G

Pre-soldered development board with switchable dual Arm Cortex-M33 and Hazard3 RISC-V cores up to 150 MHz, 520 KB SRAM, 26 GPIO pins, 24 PWM channels, and 3 ADC inputs

  • Pre-soldered header saves assembly time
  • Dual Arm Cortex-M33 and Hazard3 RISC-V cores selectable
  • 150 MHz clock with 520 KB SRAM and 4 MB flash
  • 26 GPIO pins plus 24 PWM channels for flexible I/O
  • Tutorial with MicroPython, C and Processing code included

Raspberry Pi Pico 2 Pre-Soldered Board

The KEHIPI development board ships with a Raspberry Pi Pico 2 that has its GPIO header already soldered in place. It exposes 26 multifunction pins and is ready for breadboard or perf-board work without any iron work.

Makers who want immediate prototyping vs wireless

Builders who want to start coding in MicroPython, C or Processing (Java) the moment the board arrives will appreciate the pre-soldered header and the included USB cable. Projects that require on-board Wi-Fi or Bluetooth should choose the Pico 2 W variant instead.

Switchable dual-core architecture

The microcontroller lets you select between two Arm Cortex-M33 cores or two Hazard3 RISC-V cores, both clocked up to 150 MHz. The chip provides 520 KB of on-chip SRAM and 4 MB of on-board QSPI flash for program storage.

Questions about this item

How do I attach the pre-soldered header board to a breadboard without bending the 26 GPIO pins?

Align the 26 multifunction GPIO pins with the breadboard rows, press straight down evenly across the board, and avoid rocking it side to side which bends the pins.

What on-board storage will wear out first after many reprogramming cycles?

The 4 MB on-board QSPI flash has a limited write-erase endurance and will degrade before the 520 KB on-chip SRAM.

At what clock speed does the dual Cortex-M33 or Hazard3 core hit its thermal limit during continuous load?

The flexible clock runs up to 150 MHz; sustained operation at that frequency is the first limit you will reach under heavy compute tasks.
