LILYGO T-Halow is an ESP32-S3 board with long-range WiFi HaLoW, OV2640/OV5640 camera support

ESP32-S3 WiFi HaLow board

LILYGO T-Halow is an ESP32-S3 board equipped with a WiFi HaLow module with up to 1.2km range, a connector compatible with OV2640 and OV5640 camera modules, and an 18650 battery holder for power, as well as several GPIOs for expansion. We first wrote about 802.11ah low-power long-range WiFi standard operating at 900 MHz in 2014, but adoption has been slow and we’ve seen a few 802.11ah (WiFi HaLow) chips from Newracom and Morse Micro over the years, as well as USB adapters, a Raspberry Pi HAT, a mini PCIe card, gateways, and some development boards. All those rely on a Linux host, but the LILYGO T-Halow features a TX-AH WiFI HaLow module from Taixin Semiconductor that’s controller by AT commands through an ESP32-S3 or a micro USB port. LILYGO T-Halow specifications: Wireless modules ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 […]

LILYGO T3S3 E-Paper combines ESP32-S3 WiFi & BLE SoC with LoRa module, 2.13-inch e-Paper display

ESP32-S3 LoRa E-Paper development board

LILYGO T3S3 E-Paper is an ESP32-S3 WiFi and Bluetooth LE development board with a 2.13-inch e-Paper display and an SX1262 LoRa module that should make it suitable for off-grid messsaging even under sunlight. LILYGO has made some ESP32-S3 boards with an e-Paper display and some ESP32-S3 boards with a LoRa module, but unless I’m mistaken, the T3S3 E-Paper is the first board from LILYGO that combines ESP32-S3 SoC with e-Paper display and a LoRa module. It builds upon the earlier LILYGO T3S3 board with a 0.96-inch OLED. LILYGO T3S3 E-Paper specifications: ESP32-S3-WROOM-1U wireless module SoC –  ESP32-S3FH4R2 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 2MB PSRAM Storage – 4MB SPI flash IPEX antenna connector Storage – MicroSD card slot Display – 2.13-inch e-Paper display (DEPG0213BN) with 250×122 resolution; size: 48.55 x 23.70mm Wireless 2.4 GHz […]

SunFounder PiPower 3 kit is a UPS solution for the Raspberry Pi 5 SBC

Raspberry Pi 5 UPS Solution

SunFounder PiPower 3 kit is a UPS solution designed to work with the Raspberry Pi 5, other Arm SBCs, or even MCU boards like Arduino UNO and Raspberry Pi Pico. The board delivers a stable 5V/5A output, and a 32-bit CH32V003 RISC-V microcontroller takes care of power management and battery level reporting to make sure the Raspberry Pi 5 keeps running when a power failure occurs and shutdowns gracefully when the battery level is low. The kit comes with two 18650 2,000mAh batteries that connect through a 2-pin connector, and all accessories – standoffs, acrylic case, and fan – for assembly with the Raspberry Pi 5, or other compatible boards like the Pi 4, Banana Pi BPI-M5, Radxa Rock Pi E, Orange Pi 3B, and others.   PiPower 3 kit specifications: 32-bit CH32V003 RISC-V microcontroller supporting I2C communication Input – 5V/5A via USB Type-C with PD support Output – 5V/5A […]

LILYGO T-Energy-S3 ESP32-S3 board offers 18650 battery holder, two 20-pin GPIO headers

ESP32-S3 board with 18650 battery holder

LILYGO T-Energy-S3 is an ESP32-S3 WiFi and Bluetooth IoT board with an 18650 battery holder, a USB-C port for charging and programming, and plenty of I/Os thanks to two 20-pin GPIO headers and a Qwiic connector. We’ve already covered a large number of ESP32-S3 boards and products, including some designs for battery operation such as the Tokay Lite AI camera board, LILYGO’s T7-S3 board, and Smart Bee Designs’ Bee S3 board among others. But that usually means providing a 2-pin connector and charging circuitry to connect a LiPo battery, but the T-Energy-S3 ESP32-S3 board works directly with an off-the-shelf 18650 rechargeable Lithium battery. T-Energy-S3 specifications: Wireless Module – ESP32-S3-WROOM-1-N16R8 Espressif Systems ESP32-S3R8 – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM Storage – 16 MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth PCB antenna USB – 1x USB […]

SupTronics Raspberry Pi 5 UPS HAT X1202 V1.1 takes four 18650 batteries delivering up to 25W

SupTronic Raspberry Pi 5 18650 Battery UPS HAT

For the tinkerers and DIYers out there, keeping a Raspberry Pi project running reliably, day in and day out, especially when the power is out is crucial, and previously Raspberry Pi UPS solutions have been available for years with products like Pascal Herczog’s Red Reactor, PiJuice Zero, PiVoyager, or LiFePO4wered/Pi+ and many others. But the problem with all these old solutions is that they cannot handle the power requirements of the new Raspberry Pi 5, especially when the PCIe is active and other peripherals are attached to it.  This is where the SupTronics Raspberry Pi 5 UPS HAT comes in. This new SupTronics X1202 V1.1 UPS Shield includes four 18650 batteries and can deliver 5V with a higher current output of up to 5A, or 25W of power. Additionally, it includes automatic power switching and battery level detection via I2C, an integrated fuel-gauge system, battery protection mechanisms, and fast charging support, making […]

STMicro LSM6DSV32X Edge AI motion sensor aims to extend battery life in wearables, trackers, and activity monitors

STMicro LSM6DSV32X AI motion sensor

STMicro LSM6DSV32X is a new low-power 6-axis inertial module with the company’s machine-learning core (MLC) with AI algorithms based on decision trees, a 3-axis accelerometer with a full-scale range of 32g, and a 4000 degrees-per-second gyroscope designed to measure intensive movements, impacts, and freefall height (estimation). The features of the sensors enable it to lower the power consumption for functions such as gym-activity recognition to under 6µA, while 3D orientation tracking consumes just 30µA when using STMicro’s Sensor Fusion Low-Power (SFLP) algorithm. It will be found in a range of battery-powered devices such as consumer wearables, asset trackers, and impact and fall alarms for workers or the elderly.
