SparkFun nRF52832 Breakout | Maker Minute



SparkFun’s nRF52832 breakout board provides easy access to the features of Nordic Semiconductor’s nRF52832 system-on-chip. The nRF52832 has a 32-bit ARM® Cortex®-M4F CPU, 512 kB Flash and 64 kB RAM memory, and it supports Bluetooth® Smart, ANT, and 2.4 GHz proprietary ultra-low-power wireless communication. The board breaks out the nRF52832’s 32 configurable I/O pins, offering support for SPI, I2C, UART, PWM, and ADCs. It also provides a 32.768 kHz RTC crystal, a user-programmable button and LED, and it comes pre-programmed with a serial bootloader. Arduino board definition is also available.

NimBLE – A High-Performance and Highly Configurable Bluetooth Low Energy 4.2 Stack



NimBLE – A High-Performance and Highly Configurable Bluetooth Low Energy 4.2 Stack – Will San Filippo & Sterling Hughes, Runtime

Apache Mynewt’s NimBLE is the world’s first fully open source Bluetooth Low Energy 4.2 stack for both host and controller subsystems for MCU environments. It offers highly granular configuration options such as number of slots per connection, max number of concurrent connections, multiple advertising instances, and more. The configurability enables a wide variety of use cases previously difficult to address with closed or licensed-binary stacks: such as 32 or more concurrent connections using the Nordic nRF52 chip as either Central or Peripheral, large data bursts when connected to a large number of peripherals, ability for a peripheral to connect to multiple centrals, etc. The flexibility of design and configuration also allows developers to reduce stack size in resource-limited environments.
