Bitsbox Pico 4MB

A third-party development board using the Raspberry Pi RP2040 chip, but with upgraded features compared to the official Raspberry Pi Pico.
Features:

The RP2040 microcontroller chip. The board is built around the same dual-core ARM Cortex-M0+ chip designed by Raspberry Pi, with a flexible clock speed that can run up to 133 MHz,

Built-in 264KB of SRAM and 4MB of on-chip fIash.

USB-C connector.

Up to 30 multi-functional GPI0 pins.

2 SPI,2 12C,2 UART,4 12-bit ADCs,16 controllabel PWM channels.

Size: 52x19mm

Compatible with the official Raspberry Pi C/C++ SDK as well as MicroPython and CircuitPython. The programming workflow, which involves dragging and dropping a .uf2 file onto the board's USB mass storage device, remains the same.
