Overview
1.1 Introduction
E73-2G4M04S1D is a SMD bluetooth wireless module based on
NORDIC's nRF51822 RF chip. NRF51822 has high-performance ARM
CORTEX-M0 core and Bluetooth 4.2 RF transceiver and protocol stack, and
has abundant peripheral resources such as UART, I2C, SPI, ADC, DMA,
PWM, etc.The module brings out almost all IO ports, which is convenient
for users to conduct multi-faceted development, Please see pin definitions for
details. The module has built-in PCB antenna and can connect other antennas
through IPEX. The product has obtained FCC, CE, RoHS and other
international authoritative certification reports, users do not need to worry about its performance. We use a 32MHz high
precision low temperature drift active crystal to ensure its industrial properties and s tability.
Because this module is a pure hardware SoC module, users need to program it before they can use it.
