The micro:bit V2 is a pocket-sized educational microcontroller board crafted for teaching coding, electronics, and STEM concepts. It features enhancements over the original V1—including sound capabilities, touch interaction, and better hardware performance—all while remaining intuitively programmable via MakeCode, Python, Scratch, and more.

Features :

• MicroUSB port for programming and power.
• JST-PH connector for external battery (3 V).
• 25-pin edge connector plus rings for I/O and power
• Knowles MEMS microphone with front-panel LED indicator
• On-board magnetic speaker (Jiangsu Huaneng MLT-8530)
• Integrated temperature sensor (within the nRF52833 MCU)
• Two front-facing programmable buttons (A & B) plus a multi-function reset/power button (can reset or power off when held)
• 5 × 5 red LED matrix (also usable as a light sensor)
• Red LED for power and a yellow LED indicating USB activity

Specifications :

• Main microcontroller (MCU): Nordic Semiconductor nRF52833, based on ARM Cortex-M4F, running at 64 MHz, with 512 KB flash memory and 128 KB RAM
• USB interface MCU: NXP/Freescale KL27Z (ARM Cortex-M0+), serving as the USB bridge and power management
