SKU620 module use nordic BLE 4.2 nRF52832 as MCU.And the module’s 3-side-half-hole footprint support many GPIO pin out which can be configured into UART,SPI,I2C,PWM interface, which is convenient for secondary development of customers. The module reserve uncovered copper on the bottom for heat dissipation.
SKU620 module use side SMA RF connector to support external high gain antenna with low insertion loss. Ant the SMA pads supports soldering our specially designed PCB antenna for SKU620, making the antenna low cost and high performance.
SKU620 module has its EVB board (VDU2506-EVB), which can transfer UART data to USB com port. The complex version support 485 UART to industrial machines. The fully-configured version support WiFi and Ethernet connection to TCP/IP or UDP server, making it easy to build a TWR positioning system.
