Nordic Semiconductor nRF52805 BLUETOOTH® 5.2 SoC
Nordic Semiconductor nRF52805 BLUETOOTH® 5.2 System-on-Chip (SoC) is the seventh addition to the nRF52® Series. The SoC augments the already extensive collection of wireless SoCs with an SoC in a WLCSP package optimized for small two-layer PCB designs. The nRF52805 can be applied as a network processor, allowing another MCU to leverage its connectivity. Nordic Semiconductor nRF52805 BLUETOOTH® 5.2 SoC is ideal for cost-constrained applications, including network processors, smart home sensors, health monitoring, asset tags, and toys.Features
