1. Description
HOLYIOT-21031 BLE module is based on Nordic nRF52805 SoC, the nRF52805 SoC is an
ultra-low power Bluetooth® 5.2 System on Chip (SoC) supporting Bluetooth Low Energy and
2.4 GHz proprietary protocols. It supports Bluetooth high-throughput 2 Mbps, transferring data
faster and more efficiently, and Bluetooth channel selection algorithm #2 (CSA #2), improving
coexistence and reducing interference. The radio has up to 4 dBm TX power and -97 dBm
sensitivity (1 Mbps Bluetooth Low Energy).the nRF52805 SoC device compliments the
extensive nRF52 Series platform with an SoC in a WLCSP optimized for small two-layer PCB
designs, significantly decreasing cost compared to four-layer PCBs. A 9.5 x 8.8 mm reference
layout with all ten GPIOs available is provided, requiring only 10 external passive components
(including two crystal load capacitors). nRF52805 features a 64 MHz Arm® Cortex®-M4
processor with 192 kB of flash memory and 24 kB of RAM. A wide range of analog and digital
interfaces is integrated, including a 2-channel 12-bit ADC, SPI, UART, and TWI. It is the
perfect choice for applications such as beacons, disposable medical devices, sensors, styluses,
and presenters.
