Introduction
Note: This product is out of stock, the lead time is three months, sorry for the inconvenience.
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)
