The nRF51822 is a multi-protocol, single-chip solution for ultra-low power wireless applications (ULP wirelesss applications).
It integrates Nordic’s state-of-the-art wireless transmitters while supporting Bluetooth(R) low energy and a dedicated 2.4GHz protocol stack.
The basic situation is:
2.4GHZ Multi-protocol Wireless RF
32-bit ARM Cortex M0 processor
128-bit AES hardware encryption processor
256kB flash / 32kB RAM
Programmable peripheral interface PPI
Full-featured digital interface: SPI / I2C / UART
Programmable output power: +4dBm to -20dBm
Application development and protocol stack completely independent
Fully compatible with NRF24L series
Compatible with NRF51xxx series pins
Global Independent Power Management
Operating voltage range (1.8 V ~ 3.6 V)
Specification: NRF51822 2.4G Wireless Communication Module
6 Months Warranty
This item is covered with a supplier warranty of 6 months from the time of delivery against manufacturing defects only. This is a quality product from the original manufacturer. Only manufacturing defects are covered under this warranty. Reimbursement or replacement will be done against manufacturing defects.
What voids the warranty:
If the product is subject to misuse, tampering, static discharge, accident, water or fire damage, use of chemicals & soldered or altered in any way.
It’s been a long time. Hasn’t checked yet.
Cannot get it to work with VESC. Larger model works
These are differently sized than the other nrf51822 modules in the same form factor, but they’re still the QFAA chip and the pins are still 2.0mm instead of 2.54mm
Very long delivery. A similar product, bought simultaneously with this came 3 weeks ago.
