TTGO T-Block modular ESP32 devkit supports “Trolley” covers acting as display, buttons, sensor, proto area, etc…

When I first LilyGO TTGO T-Block ESP32 devkit with an enclosure and a display it reminded me of the M5Stack Core2 devkit, but it’s actually different as LilyGO designed a modular system that allows users to change the functionality of the top cover with expansion boards called “Trolleys”. That means TTGO T- Block can be fitted with a small e-Ink display, a prototyping cover, an RGB LED matrix, a small board that supports various MQ gas sensors, touch buttons, or a Trolley board equipped with headers compatible with common Arduino modules. TTGO T-Block Host 9102 preliminary specifications: WiSoC – ESP32 dual-core processor @ 240 MHz with 520KB SRAM, WiFi 4 and Bluetooth LE 4.2/5.x connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash, MicroSD card slot USB – 1x USB Type-C for power and programming via CH2104 USB to TTL chip Trolley interface – 20-pin connector with 17x GPIO, […]

Bluetooth LE 5.0 module enables batteryless sensors thanks to Renesas RE01B MCU

RELOC RM-BE1 BLE 5.0 module energy harvesting

RELOC RM-BE1 Bluetooth 5.0 module with embedded energy harvesting capabilities for batteryless sensors adds to the list of energy harvesting news we’ve written about since the beginning of the year, with UEI chip for remote controls, a devkit with a smart coffee cup, and Atmosic ATM33 BLE 5.3 chip. The RM-BE1 module is powered by Renesas RE01B Arm Cortex-M0+ Bluetooth microcontroller that leverages Renesas’ SOTB (Silicon on Thin Buried Oxide) process technology enabling ultra-low power. We’ve been told the chip can run at 35uA/Mhz with internal LDOs and <20uA/Mhz with additional external DCDCs, as well as around 600nA in standby mode. RELOC RM-BE1 module key features and specifications: MCU – Renesas RE01B Arm Cortex-M0+ microcontroller @ 64 MHz with 1.5MB flash, 256KB SRAM Connectivity Bluetooth LE 5.0 with Long Range (up to 400 m) and high data throughput (2 Mbps) support RF output power – Up to +4 dBm Receiver […]

Wiliot Starter Kit for retailers features a smart coffee cup tracking temperature, fill level, location, etc…

smart coffee cup with sensors, energy harvesting

Wiliot Starter Kit aims to demonstrate the ability of the Wioliot’s self-powered IoT Pixel and cloud services to retailers with a kit including a Coffee cup that’s capable of tracking liquid temperatures, fill level, motion, location changes, humidity, and proximity. The kit was previously only available to larger retailers through a “controlled release model”, but the company has now switched to an “open model” so that any retailers can use the technology to track products and packages. Let’s what’s included inside the start kit, and try to understand how the Wiliot solution works. Wiliot Starter Kit includes the following hardware: 1 x IoT Pixel-ready Coffee Cup 5 x Single-Band IoT Pixels mounted on cardboards 5 x Dual-Band IoT Pixels mounted on cardboards 1 x Single-Band Bridge Device 1 x Dual-Band Bridge Device You’ll also get 6 months of Wiliot Cloud Services, access to the Wiliot community forum & support Portal, […]

Microchip SAM L22 board makes Casio F-91W watch more customizable (Crowdfunding)

Casio F-91W is a popular watch that was first released in 1989, and it is still sold today for around $15. The team at “Oddly Specific Objects” decided to create the “Sensor Watch” open-source hardware board based on Microchip SAM L22 Cortex-M0+ microcontroller that can replace the electronics inside the watch. They still keep the display and enclosure and wristband from the original Casion F-91W watch, but the new board connects to a temperature sensor board, and more importantly, provides the ability to hack/program the watch with your own code, besides the few samples provided, or even design your own sensor board. Sensor Watch board specifications: MCU – Microchip SAM L22 Arm Cortex M0+ microcontroller @ 32 MHz with 32KB RAM, 256 KB of Flash with up to 16 KB EEPROM emulation area Display – Controller for 10-digit segment LCD, plus five indicator segments USB – 1x Micro USB PCB […]

Onera Health unveils Onera Biomedical-Lab-on-Chip with over a dozen sensor inputs

Onera Health, a Dutch-American MedTech company has just introduced the Onera Biomedical-Lab-on-Chip, an ultra-low-power biosignal sensor hub for wearable health, following their earlier work on sleep diagnostic solutions. The Arm Cortex-M4F based Onera ONE010 chip embeds a multi-channel sensor readout system with integrated data processing, power management, and interfacing features. It features biomedical inputs with 10 readouts for ExG, covering EEG, ECG, EMG, and EOG, 2 bioimpedance readouts, and 2 readouts for photoplethysmography, as well as digital filters and accelerators to process the data from the sensors. The microcontroller is also equipped with several standard wired interfaces such as UART, SPI, I2C, and I2S, operates from a single power source between 0.8V and 3.6V, and the company says a large amount of SRAM and embedded FLASH is available. I’ve managed to obtain a more readable block diagram and that means 320KB of SRAM and 768KB of flash. We can also […]

NOVELDA UWB X4 sensor can detect submillimeter movements

We’ve just written about an ESP32 UWB board equipped with an ultra-wideband module designed for indoor positioning with about 10 centimeters accuracy, which should be good enough for many applications, but it turns out UWB sensors can be made to be much more accurate. NOVELDA has just announced the UWB X4/X4F103 sensor and development kit that can detect submillimeter micro-movements such as breathing for human presence detection and does so at a really low power consumption of under 2mW. NOVELDA UWB X4 (X4F103) highlights: High-precision ranging for accurate distance measurement and absolute range bounding based on patented impulse radar technology Low power consumption below 2mW, and no co-existence issues with other sensors Wide detection zone for accurate detection with up to 180-degree field of view Up to 5m range Works through plastic and glass or layers of clothing Package – 12 x 12mm sensor A big difference compares to Decawave […]
