## Description

**Introduction**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](https://www.dfrobot.com/product-2125.html).

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)
