The NRF51822 Bluetooth Low Energy mbug board from y5 Design is an easy to use ARM Cortex-M0 microcontroller with BLE. This board can be used as a standalone system or stacked with other mbugs to create multifunctional systems.
Part of mbug ecosystem
- Smaller than a quarter, at approximately 0.9" x 0.9"
- Can be used as a standalone microcontroller or with other mbugs (sensors, displays, relay, servo, battery, etc.)
- 12 different mbugs (2 processors, 9 expansion, 1 prototype)
- stackable 100-mil pitch dual 8-pin connector
- standardized pinout strategy to ensure interoperability
- supports standard interfaces (USB, UART, SPI, I2C)
