Description
This chip has twice the flash, SRAM and performance of the earlier nRF51-based Bluefruit modules. Best of all, it has Arduino IDE support so there is no 'helper' chip like the ATmega32u4 or ATSAMD21. Instead, this chip is programmed directly! It's got tons of awesome peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Leaving out the extra microcontroller means the price, complexity and power-usage are all lower/better. It allows you to run code directly on the nRF52832, straight from the Arduino IDE as you would with any other MCU or Arduino compatible device. A single MCU means better performance, lower overall power consumption, and lower production costs if you ever want to design your own hardware based on your Bluefruit nRF52 Feather project.

Q: What are the key features of the Feather nRF52 Bluefruit LE nRF52832 ARM Cortex M4F?
A: The Feather nRF52 Bluefruit LE nRF52832 ARM Cortex M4F is a development board that features an ARM Cortex M4F processor running at 64MHz, 512KB of flash memory, and 64KB of SRAM. It also includes a built-in USB serial converter for programming and debugging, Bluetooth Low Energy compatibility, an FCC / IC / TELEC certified module, up to +4dBm output power, 1.7v to 3.3v operation with internal linear and DC/DC voltage regulators, 19 GPIO, 8 x 12-bit ADC pins, up to 12 PWM outputs, a red LED for general purpose blinking, a power/enable pin, and measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in.
Q: What is the difference between the Feather nRF52 Bluefruit LE and the Feather 32u4 Bluefruit LE?
A: The main difference between the Feather nRF52 Bluefruit LE and the Feather 32u4 Bluefruit LE is the processor. The Feather nRF52 Bluefruit LE uses an ARM Cortex M4F processor, while the Feather 32u4 Bluefruit LE uses an ATmega32u4 processor. The Feather nRF52 Bluefruit LE is also more powerful, with twice the flash memory and SRAM of the Feather 32u4 Bluefruit LE.
Q: Does the Feather nRF52 Bluefruit LE require a helper chip like the ATmega32u4 or ATSAMD21?
A: No, the Feather nRF52 Bluefruit LE does not require a helper chip like the ATmega32u4 or ATSAMD21. This is because the nRF52832 processor is integrated into the chip itself.
Q: What are some of the benefits of using the Feather nRF52 Bluefruit LE?
A: Some of the benefits of using the Feather nRF52 Bluefruit LE include its ease of use (it can be programmed directly from the Arduino IDE), its lower power consumption, and its better performance.
