IndieSemiC EVK-ISC-nRF52810-A Nordic Semiconductor nRF52810 BLE 5.2 Module Dev Board

This module is fully compatible with Nordic Semiconductor Semiconductor's nRF5 SDK and the newer nRF Connect SDK (based on Zephyr RTOS). You can develop applications using the Segger Embedded Studio IDE, ARM Keil, or IAR Embedded Workbench. For BLE prototyping, Nordic Semiconductor's nRF Connect for Desktop provides essential tools like the Bluetooth Low Energy sniffer and Power Profiler. The board supports programming and debugging via the SWD interface using a compatible Segger or CMSIS-DAP debug probe.

The nRF52810's transmit power is software-configurable via its radio peripheral registers, typically set within your firmware using the Nordic Semiconductor SDK API. Power levels range from -20 dBm to +4 dBm in 4 dB steps. The achievable range depends heavily on antenna design, environment, and data rate. With the integrated PCB antenna, +4 dBm output, and -96 dBm sensitivity, you can expect a reliable line-of-sight range of several tens of meters in open air for BLE communication, though obstacles will reduce this.

The module exhibits ultra-low power consumption critical for battery operation. In active radio transmission or reception at 0 dBm, peak current is around 4.6 mA. The nRF52810 SoC supports multiple low-power modes: SYSTEM_ON low-power mode retains RAM and peripherals at microamp currents, while deep sleep (SYSTEM_OFF) shuts down everything except wake-up sources, drawing less than 1 µA. You must manage GPIO states and peripheral clocks in firmware to minimize sleep current. Power draw scales with supply voltage within the 1.7V to 3.6V range.
