9 The nRF51 series is the first series for short range wireless applications.
10 It is superseded by the nRF52 series.
11 The following machines are based on this chip :
13 - ``microbit`` BBC micro:bit board with nRF51822 SoC
15 There are other series such as nRF52, nRF53 and nRF91 which are currently not
21 * ARM Cortex-M0 (ARMv6-M)
25 * Random Number Generator (RNG)
34 * Real-Time Clock (RTC) controller
37 * Analog to Digital Converter (ADC)
44 The Micro:bit machine can be started using the ``-device`` option to load a
45 firmware in `ihex format`_. Example:
