Module introduction
The module is based on Nordic’s nRF52840 (6*6) design, using high-precision four-layer board design, SMD packaging, and IPEX interface design. The module works in the 2.4 GHz ISM Band and complies with BQB, FCC, CE, ROHS and other certification specifications.
Customers with Bluetooth BLE protocol stack application capabilities are supported to write their own Bluetooth firmware. nRF52840 has a 32-bit ARM Cortex M4F core with 1MB Flash + 256KB RAM and supports the BLE 4.2/5.0 Bluetooth protocol stack. The hardware has rich analog and digital peripherals such as UART, I2C, SPI, PWM, ADC, etc., which can meet various design needs.
Support customers with MCU development capabilities to use our factory-burned transparent transmission program (master-slave mode, scan mode, host mode) and other functions to achieve:
MCU<—>UART<—>EW-MOD03PA (Host Mode/Scan Mode)<—>Bluetooth Slave/Beacon
