ISC-nRF54L05-A Bluetooth 6.0 Multiprotocol Module with Nordic nRF54L05, Integrated Antenna and FCC/CE/WPC Certification
The ISC-nRF54L05-A is a Made-in-India, ultra-low-power Bluetooth 6.0 wireless module built around the Nordic Semiconductor nRF54L05 SoC. Designed and manufactured by IndieSemiC, the compact 36-pin castellated SMD module combines a 2.4 GHz multiprotocol radio, 128 MHz Arm Cortex-M33 processor, RISC-V coprocessor, and integrated PCB trace antenna in a single package. It supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, Matter, proprietary 2.4 GHz communication and NFC-A, allowing one hardware platform to support multiple wireless product architectures through firmware configuration.
The nRF54L05 provides 500 kB RRAM and 96 kB RAM, together with TrustZone, FPU and a hardware cryptographic engine supporting 128-bit AES, ECB, CCM and AAR operations. Its Bluetooth 6.0 radio supports Channel Sounding, BLE data rates from 0.125 Mbps to 2 Mbps, and proprietary communication up to 4 Mbps. Adjustable transmit power from -8 dBm to +8 dBm, receiver sensitivity down to -103 dBm in Coded PHY mode, and IEEE 802.15.4-2020 support make the module suitable for low-power mesh, smart-home, and proximity applications.
For embedded development, the module provides 29 GPIO pins across 3 power domains, up to 5 EasyDMA-enabled serial interfaces, I2S, an 8-channel ADC, PWM, timers, QDEC, RTC resources and a temperature sensor. Operating from 1.7 V to 3.5 V, it is well suited to coin-cell, Li-ion, and LiPo-powered products. Typical measured consumption is approximately 1.32 uA in System OFF mode and approximately 229 uA during BLE advertising at +4 dBm with an approximately 100 ms interval. The module is FCC, CE, and WPC ETA certified, helping simplify module-level wireless integration; final-product regulatory compliance remains the responsibility of the equipment manufacturer.
