1、Module description: NRF24LE1 is a cost-effective and built-in microcontroller intelligent 2.4GHz RF transceiver in the family of a member of the. NRF24LE1 is optimized for ultra low power wireless applications. Capability of processor, memory, low power oscillator, real name, counters, AES encryption accelerator, the combination of the random number generator and power saving mode to implement RF protocol provides an ideal platform. The benefits of using nRF24LE1 include tight protocol timing, security, low power consumption, and improved coexistence performance. For application layer, nRF24LE1 provides a rich peripherals including: SPI, IIC, UART, 6 to 12 bit ADC, PWM and a super low power analog comparator for voltage level system wake-up. 2、Function Description: Hz nRF24L01+2.4 transceiver (250 BPs, 1 Mbps, 2 Mbps air rate)
