Характеристики

RF-BM-ND08A is an RF module based on Nordic BLE SoC nRF52811QFAA with ARM^®Cortex^®-M4 32-bit processor. It integrates a 32.768 kHz and a 32 MHz crystal, an LC filter, an antenna matching and a meander line inverted-F PCB antenna. It features low power consumption, robust connection distance, and rigid reliability. It supports BLE5.2,  Direction Finding and Thread, and can be preprogrammed with a serial interface communication protocol for simple programming. It includes a range of analog and digital interfaces such as ADC, PDM, PWM, UART, SPI and I²C. 1.27-mm pitch stamp stick package for easy assembling and cost-effective PCB design. RF-BM-ND08A is pin-to-pin compatible with RF-BM-ND08.
