The wireless module supports 2.4 GHz and 5 GHz Wi-Fi 6, Bluetooth LE 5.3, Zigbee, and Thread connectivity. It integrates an ESP32-C5 32-bit RISC-V single-core microprocessor running up to 240 MHz with 320 KB ROM, 384 KB high-power SRAM, and 16 KB low-power SRAM. The N8R4 configuration denotes 8 MB Quad SPI flash and 4 MB PSRAM. It operates from a 3.0 V to 3.6 V supply over a -40 °C to 85 °C ambient temperature range and uses an onboard PCB antenna in an 18.0 mm × 27.5 mm × 3.3 mm module body.
