BLE modules delivered in LL and HT variants
These modules are designed to provide huge computing capability with the best battery life. They are based on a Nordic Semiconductor nRF52 wireless system-on-chip (SoC) that integrates a 2.4 GHz transceiver and a 32-bit Arm Cortex-M4 CPU.
Bluetooth Low Energy, ANT/ANT+, Thread, Zigbee and a range of proprietary 2.4 GHz protocols are all supported by the modules.
They are available in LL and HT variants.
The LL variant modules feature 192 kBytes of flash and 24 kBytes of SRAM, and offer 13 configurable GPIOs including three analogue-to-digital converters (ADCs).
The HT variant modules provide 512 kBytes of flash and 128 kBytes of SRAM, and offer 30 configurable GPIOs including eight ADCs.
The ISP1907 modules operate at a 1.7V to 3.6V voltage range and provide pin compatibility with ISP15, ISP18, and ISP19 Bluetooth Low Energy modules.
Applications for the ISP1907 modules include Internet of Things (IoT) devices, wearable technology, home automation, and beacons.
