The Bee Data Logger ESP32-S3 board comes with RTC, microSD slot, and two Qwiic connectors for sensors

ESP32 Data Logger

A few months ago, SparkFun released the “Datalogger IoT – 9DoF” no-code platform based on ESP32 with some built-in sensors, a microSD card, and two Qwiic connectors to add sensors in order to perform data logging with minimal to no coding. Smart Bee Designs looks to have shrunk the design, removing the built-in sensors in the processor, with the Bee data logger ESP32-S3 board that offers most of the same features plus a built-in DS3231 RTC and back battery for timekeeping, and the ability to leverage the vector extension in the ESP32-S3 for machine learning applications. Bee data logger specifications: Wireless module – Espressif Systems ESP32-S3-MINI-1 module CPU – ESP32-S3 dual-core Xtensa LX7 microcontroller with vector extensions with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity Storage – 8MB of QSPI flash PCB antenna Storage – MicroSD card slot up to 16GB capacity USB – 1x USB Type-C port […]

An ESP32-S3 board for vending machines with RS485, microSD card slot, optional cellular mPCIe module

LILYGO T Vending

LILYGO T-Vending is an ESP32-S3 WiFi and Bluetooth IoT board designed for vending machines with an RS485 terminal block, a microSD card slot, and support for an optional cellular mPCIe module. As I understand the board is connected to the vending machine through the RS485 terminal block to control vend motors (potentially via an additional board to control multiple motors) and a 10-pin connector for power (12V/24V), signals to/from a coin mechanism and other parts. The board also adds a Grove connector and an unpopulated 12-pin GPIO header for expansion. T-Vending specifications: ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Wireless 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity (ESP32-S3) Optional T-PCIe 4G LTE […]

WeAct launches $6 ESP32-C6 development board, ESP-IDF 5.1 framework released

WeAct ESP32-C6 development board

As expected, Espressif has just released the ESP-IDF 5.1 framework with ESP32-C6 and ESP32-H2 support, so more ESP32-C6 boards should become available, and after Olimex ESP32-C6-EVB launched earlier this week, we’ve noticed WeAct had introduced a low-cost ESP32-C6 development board that sells for just $6.43 plus shipping a few weeks ago. WeAct ESP32-C6 board The WeAct board offers 2.4 GHz WiFi 6, Bluetooth LE 5.0., and Zigbee/Thread connectivity through the ESP32-C6-WROOM-1 module, two USB-C ports, two 16-pin headers for GPIOs, and if it looks familiar, it’s because it closely follows the design of the official ESP32-C6-DevKitC-1 development kit, albeit with some small modifications. WeAct ESP32-C6 board specifications: Wireless module  – ESP32-C6-WROOM-1 with ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz, with 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless – 2.4 GHz WiFi 6, Bluetooth 5.0 LE, 802.15.4 radio for Zigbee 3.0 and Thread.

$26 WiFi 6 router board features Triductor TR6560 & TR5220 chips

Banana Pi BPI WiFi 6 board

Banana Pi BPI-Wifi 6 is an ultra-low-cost WiFi 6 router board with five Gigabit Ethernet ports based on Triductor Technology TR6560 dual-core Cortex-A9 router SoC and TR5220 WiFi 6 chipset and that sells for just $26.32 plus shipping on Aliexpress, or $39.99 as part of a kit with the board, four antennas, and a 12V power supply. The board is equipped with 512MB RAM and a 128MB SPI flash for OpenWrt, comes with four antenna connectors for WiFi, and can also take an optional 12V PoE module for power instead of relying on a 12V power adapter via a DC jack. Banana Pi BPI-WiFi 6 board specifications: SoC – Triductor TR6560 dual-core Arm Cortex-A9 processor @ 1.2 GHz with LSW (Line-Card Switching) and hardware NAT up to 5 Gbps WiFi chipset – Triductor TR5220 WiFi 6 chipset System Memory – 512 MB DDR3 Storage – 128MB SPI NAND flash Networking […]

64-core RISC-V motherboard and workstation enable native RISC-V development (Crowdfunding)

64-core RISC-V motherboard

There’s now a microATX motherboard and workstation for native RISC-V development based on the SOPHON SG2042 64-core RISC-V C920 processor with up to 128GB DDR4 memory, various SATA and M.2 NVMe interfaces for storage, three PCIe x16 slot for expansion and more. I remember a few years ago, there was a lot of talk about making a workstation for native Arm development instead of relying on x86 machines, cross-compilation, and emulation. So we got hardware like the HoneyComb LX2K, Ampere eMAG, and more recently the ADLINK Ampere Altra Dev Kit to achieve this goal. The RISC-V ecosystem is now getting something similar thanks to the Milk-V Pioneer microATX motherboard and the Pioneer Box that provides a complete 64-core RISC-V workstation with DIMM memory, SATA and NVMe storage, a graphics card, 10GbE networking, a 350W power supply, and more. Pioneer board specifications: SoC – Sophgo SOPHON SG2042 64-core RISC-V processor (T-Head […]

Qualcomm IPQ9574 “AL02” router board support WiFi 7 modules, 10GbE networking

Wallys DR9574 WiFi 7 board

The recent Linux 6.4 release included initial support for the AL02 WiFi 7 router board powered by a Qualcomm IPQ9574 quad-core Cortex-A73 processor part of the Qualcomm Networking Pro 1620 platform with the board featuring 2GB DDR4 RAM and 256MB NAND flash. A couple of weeks ago, I was contacted by Wallystech about their DR9574 WiFi 7 board based on the IPQ9574 processor, but I ended up not writing about it due to the lack of information and low-quality photos. But it turns out it’s actually the Qualcomm AL02 reference board that’s also provided by Compex. Both companies are world-leading in the sense they offer low-quality and blurry pictures in a way that’s unmatched in the industry, but we do have some specifications, so let’s have a closer look. AL02 / DR9574 board specifications: SoC – Qualcomm IPQ9574 quad-core Arm Cortex-A73 processor @ 2.2GHz processor System Memory – 2GB DDR4 […]
