## Description

Willkommen, Calliope Mini! Developed in Germany for students in primary school and up, this heavenly star-shaped development board is a souped-up derivative of the micro: bit.The main chip on the Calliope is the same nRF51822 as the micro: bit so for many purposes, it can be programmed the same way. There are some big upgrades though!Things that are the same as the micro: bit Nordic nRF51822 Multi-protocol Bluetooth® 4.0 low energy / 2.4GHz RF SoC 32-bit ARM Cortex M0 processor (16MHz) 16kB RAM 256kB Flash Bluetooth low energy 5x5 LED matrix display USB Micro B connection (programming and power supply) JST battery connector (3.3V) 2 programmable buttons PWM outputs NXP KL26z (USB UART and programming interface chip) Serial interface (USB + configurable ports) 4 analog inputs 8-11 Input / Output Connections (depending on software configuration) SPI + I2C Things that are new or different: Instead of edge-connect pads on the bottom of the board, like the micro: bit, Calliope Mini's has a circular star design, with alligator pads on 6 corners for easy connection. Full 9 degrees of freedom IMU with Accelerometer, Gyroscope, Magnetometer (Bosch BMX055) - the micro: bit has only accelerometer and magenetometer, and they are different/separate chips. MEMS Microphone for audio input DC Motor Driver (TI DRV8837) to drive a single DC motor or solenoid Piezo Speaker RGB LED (WS2812B NeoPixel) 2 x Grove connectors (I2C + serial / analog) SPECIFICATION Nordic nRF51822 Multi-protocol Bluetooth® 4.0 low energy / 2.4GHz RF SoC 32-bit ARM Cortex M0 processor (16MHz) 16kB RAM 256kB Flash Bluetooth low energy Operating/Supply Voltage: 3.3V
