Description

The NRF52810-QCAA-R is the third member of the nRF52 Series SoCs. It features a powerful CPU (ARM Cortex-M4) and, together with the nRF52840 and nRF52832, forms Nordic's full Bluetooth 5-enabled product line, providing a full range of Bluetooth 5 possibilities for your product design. The nRF52810 supports the key features of Bluetooth 5, including high throughput (2Mbps) and enhanced broadcast capacity and advertising extensions (x 8). As an optimized solution, it is very attractive in a wide range of applications from both a performance and lowest bill of materials (BOM) perspective. The nRF52810 and all nRF52 Series are flash-based SoCs, so over-the-air firmware upgrades are fully supported.

Pin definition (QFN-32 package key pins)

Typical application circuit

   1. BLE beacon design

       NRF52810 ──── Peripheral devices

            VDD ──── 3V button battery (CR2032)

            P0.05 ──── LED (220Ω resistor in series)

            P0.12 ──── Temperature sensor (such as DS18B20)

            ANT ──── PCB antenna (inverted F design)

   2. PCB layout points:

       - RF part:

           1. ANT pin routing needs 50Ω impedance control, length ≤15mm.

           2. Avoid copper plating or placing other signal lines in the RF area.

       - Power decoupling:

           1. The VDD pin needs to be connected in parallel with a 4.7μF (low frequency) + 100nF (high frequency) capacitor.
