Telink energy harvesting wireless module to enable batteryless remote controls

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.

tCam-Mini IR thermal camera board ships with ESP32 module

While there are plenty of ESP32 camera boards, it’s much harder to find off-the-shelf solutions with ESP32 wireless SoC and an IR thermal camera. That’s likely why Dan Julio decided to design tCam-Mini board combining an ESP32 module with a Flir Lepton 3.5 sensor with 160×120 resolution to capture radiometric data for thermographic analysis. tCam-Mini board hardware specifications: Wireless module – Espressif ESP32-WROVER-E module with dual-core ESP32-D0WD0V3 WiSoC, 8 MB PSRAM, 8 MB Flash, and PCB antenna; Camera – Flir Lepton 3.5: 160×120 pixel radiometric LWIR camera with shutter operating in either Radiometric/TLinear (each pixel contains temperature data) or AGC modes (no temperature data in each pixel but better images). Expansion – 4-pin I2C header Debugging – Micro USB port with CP2102N-A02 USB to UART bridge for ESP32 boot loader control Misc – Dual color (Red/Green) status LED, Factory/Wifi Reset button Power supply – 5V input via micro USB port […]

Firefly dual-lens AI camera module comes with Rockchip RV1109 or RV1126 processor

We’ve very recently written about Rockchip RV1126 quad-core Cortex-A7 processor designed AI cameras thanks to a 2.0 TOPS AI accelerator together with its little dual-core brother: RV1109. We’ve also found some RV1109 and RV1126 evaluation boards, but prices were in the hundreds of dollars. It was then brought to our attention than the upcoming MAIX-III board would feature RV1126 at a more affordable cost, but it turns out there’s no need to wait as Firefly has just launched a dual-lens AI camera module based on either Rockchip RV1109 or RV1126 for under $100 with respectively CAM-C1109S2U and CAM-C1126S2U models. Both version of the modules have the same specifications except for the processor: SoC (one or the other) RV1109 SoC with CPU – Dual-core Arm Cortex-A7 @ 1.5 GHz + RISC-V MCU @ 400 MHz GPU – 2D graphics engine NPU – 1.2 TOPS with support for INT8/ INT16 VPU Encoder […]

Beware of Defective, Wrongly Manufactured IR Thermometers

There is a lot of demand for medical supplies and equipment due to COVID-19. IR Thermometers are used to check the temperature of people before entering a building for instance and are also in short supply. So factories are frantically mass-producing everything they can from face masks to IR thermometers, and it looks like some may forgo quality control.  The latter are very hard to find in Thailand, but one person managed to purchase an IR thermometer online and decided to open it… [Update April 16th 2020: The Facebook video has been taken down, but still available on Youtube] This Heaco MDI908 medical thermometer’s infrared board is not connected to the mainboard, so it “works” even without the IR sensor… This takes “non-contact infrared thermometer” to a whole new level 🙂 I can see Kaidee (Thailand’s eBay) had some listed a few days, but the pages have since then been […]
