Telink energy harvesting wireless module to enable batteryless remote controls

Telink Energy Harvesting Multi protocol Wireless module TV remote control

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. The solution is based on a 48MHz RISC microcontroller that supports Bluetooth 5.1 LE, 802.15.4 (Zigbee/RF4CE/6LoWPAN/Thread), and 2.4GHz proprietary protocols. With a single module integrating all main components required for batteryless operation, Telink says its solutions reduce BOM and size, as well as supply chain complexity, and improves user-friendliness by removing the need for battery swaps. Telink TLSR8273-M-EH specifications: Core – 32-bit RISC microcontroller @ up to 48 MHz (CoreMark 1.25/MHz) Memory – 64 KB SRAM with 32 KB retention Storage – 512 KB flash RF Bluetooth 5.1 LE up to 2 Mbps, with AOA/AOD support, Bluetooth Mesh IEEE 802.15.4 radio for Zigbee, RF4CE, 6LoWPAN, Thread 2.4GHz proprietary protocols RX […]

Espressif unveils “One-Stop Matter Solution” for ESP32 wireless SoC’s

Espressif Systems have announced their one-stop Matter solution that features their ESP32, ESP32-C, and ESP32-S series wireless microcontrollers with WiFi and/or Bluetooth LE connectivity, as well as the ESP32-H series with an 802.15.4 radio for Thread and Zigbee connectivity. Matter, which was first introduced in 2019 as Project CHIP, aims to improve interoperability among Smart Home products, has a focus on security, and the protocol is supposed to work on top of the most popular communication standards like Ethernet, Thread, 802.15.4, WiFI, Bluetooth, and so on, but more on that later. The first commercial products with support for Matter are scheduled for the end of the year, so all major vendors of wireless chips have already introduced Matter-ready solutions including NXP, Silicon Labs, Nordic Semi, and others. Espressif had actually already talked about Matter support with the announcement of the ESP32-C2 chip. But the recent announcement targets all Espressif’s ESP32 […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]
