Telit energy harvesting wireless module to enable batteryless remote controls - CNX Software
Summary
Telink TLSR8273-M-EH is a multi-protocol wireless connectivity module with energy harvesting capabilities implemented through Nowi’s PMIC, and designed for batteryless devices (or ones with “forever batteries”) such as TV remote controls, but also wearables, and electronic shelf labels among others. With a single module integrating all main components required for batteryless operation, Telit says its solutions reduce BOM and size, as well as supply chain complexity, and improves user-friendliness by removing the need for battery swaps. • RF • Bluetooth 5.1 LE up to 2 Mbps, with AOA/AOD support, Bluetooth Mesh • Peripheral interfaces • Up to 6 channels of differential PWM • Power management • Current Consumption (25°C): • Deep Sleep with 32 KB SRAM retention, with 32K RC oscillator on: 3 uA The TLSR8273-M-EH module is compatible with Telink’s SDKs, and the company says that besides solar-powered BLE/IR/RF4CE remote controls, BLE wearables, and proprietary shelf labels, the module can also be integrated into HID devices, Smart Home products, health and wellness devices, as well as location services using both RSSI and AOA/AOD. I can’t find any recent information related to the NB-IoT V2 module, so I’m not sure what happened here, many sanctions got in the way with Hisilicon being part of Huawei, and Nowi being based in the Netherlands. Telink does not have a product page for its energy harvesting wireless module, but more details can be found in a PDF datasheet and the press release.
