M5Stack Tab5 Review – Part 1: Unboxing, teardown, and first try of the ESP32-P4 and ESP32-C6 5-inch IoT devkit

M5Stack Tab5 Review Camera Test

I’ve just received a review sample of the M5Stack Tab5 ESP32-P4 IoT development kit, which looks like a small tablet with a 5-inch touchscreen display, a 2MP front-facing camera, an ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless module, and various expansion interfaces. Today, I’ll go through an unboxing, a (partial) teardown, and have a quick try with the default firmware and GUI, before checking out how to program the device in the second part of the review. M5Stack Tab5 unboxing I received the Tab5 in its retail package along with an M5Stack-branded transparent sticky tape roll. Not sure why, but thanks M5Stack, sticky tape is always useful, so appreciated! The bottom side of the package has all the key features and specifications that we already covered in our article about the Tab5. The package contains the Tab5 itself, a 2,000mAh/14.8Wh battery, and a cable with six wires for the ExtPort2 […]

$24 Lucky Miner SOLO-LV02 is the equivalent a lottery ticket for Bitcoin mining

Lucky Miner SOLO-LV02

Bitcoin mining now requires expensive machines, so I was surprised when I saw the Lucky Miner SOLO-LV02 cryptocurrency mining “machine” going for about $24 on AliExpress (link at the end of this post). The USB-powered box is capable of mining coins with the SHA-256 algorithm, and features a 1.9-inch display, WiFi connectivity, and two buttons. In theory, we’re told the device can mine BTC, BCH, BSV, DGB… Considering the really low hashrate, it’s the equivalent of a lottery ticket for Bitcoin or other cryptocurrencies, and the luckiest ones may get one Bitcoin block (3.125 BTC). SOLO-LV02 specifications: SoC – Unnamed Hashrate – 72kH/s ±10% Algorithm SHA-256 Display – 1.9-inch color TFT display Connectivity – WiFi USB – 1x USB Type-C port for button Misc Top button for menu selection, factory reset, and configuration mode activation Bottom button for screen on/off and orientation Power Supply – 5V via USB-C port Power Consumption […]

ThinkNode M2 ESP32-S3-based Meshtastic handset features 1.3-inch OLED display, 1,000 mAh battery

ThinkNode-M2 Meshtastic Messenger

Elecrow ThinkNode M2 is yet another Meshtastic handset for off-grid messaging and GPS coordinate sharing based on an ESP32-S3 module providing Bluetooth connectivity to a smartphone, and a Semtech SX1262 LoRa transceiver for low-power long-range wireless connectivity. It’s an evolution of the ThinkNode-M1, itself similar to the LILYGO T-Echo, based on a Nordic Semi nRF52840 Bluetooth module and SX1262 LoRa transceiver with an external antenna housed in a 3D printed enclosure. The new ThinkNode M2 is very similar but features a more powerful ESP32-S3 module instead, relies on a 1.3-inch OLED display instead of a 1.54-inch e-paper display, and is housed in an ABS plastic case. ThinkNode M2 specifications: Core module – ESP32-S3 module (looks to be ESP32-S3-WROOM-1 on the photo below) SoC – ESP32-S3 CPU – dual-core 32-bit microcontroller @ 240MHz Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM 4MB flash Wireless – 2.4GHz Wi-Fi and Bluetooth […]

M5Stack Tab5

The M5Stack Tab5 may look like a small tablet, but it’s an ESP32-P4 IoT development kit with a 5-inch touchscreen display, a 2MP front-facing camera, an ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless module, and a range of interfaces. Those include USB Type-A and Type-C ports, an RS485 interface, a STAMP pad to connect an LTE Cat M/NB-IoT or LoRaWAN module, and expansion connectors including a Grove module, a 30-pin M5Bus header, and a GPIO_EXT connector. The Tab5 is also equipped with a built-in speaker and dual-microphone array, and the ESP32-P4 development kit is powered by a removable battery with charging support. M5Stack Tab5 specifications: Microcontroller – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz with 8KB of zero-wait TCM RAM Memory 768 KB HP L2MEM […]
