ThinkNode M1/M2 Review – Getting started with Meshtastic

I’ve been writing about Meshtastic firmware and hardware since 2020, but I never had the opportunity to test it myself. This has now changed as Elecrow sent us the ThinkNode M1 and ThinkNode M2 Meshtastic nodes for review. Both rely on Semtech SX162x radios, but the M1 is based on a Nordic Semi nRF52840 Bluetooth MCU with a 1.54-inch E-Ink display and GPS, and the smaller M2 is based on an ESP32-S3 chip and a 1.3-inch OLED but lacks a built-in GPS module. Since I’ve never used Meshtastic before, this “review” will be more like a Getting Started Guide from a beginner’s perspective. After an unboxing and a teardown, I’ll test messaging, GPS sharing, and the range I can get in a suburban environment in Thailand. ThinkNode M1/M2 unboxing Both packages look similar, with a plastic case and a white cover. The ThinkNode M1’s main features include a high-gain antenna, […]

WisMesh Board ONE allows you to build a custom Meshtastic Node with OLED, GPS, battery, enclosure, and more

There are now plenty of Meshtastic hardware platforms for off-grid messaging, audio communication, and GPS coordinate sharing, be it boards or modules for DIY projects, or complete solutions with battery and enclosure working out of the box, such as the Wio Tracker L1 Pro or ThinkNode M2, among many others. In some ways, RAKwireless’ WisMesh Board ONE baseboard offers the best of both worlds, combining the flexibility of DIY designs with the convenience of complete solutions, as it allows users to create a custom Meshtastic node with optional OLED, GPS, battery, antennas, and enclosure besides the usual choice between 868 MHz and 915 MHz LoRa radios. WisMesh Board ONE specifications: Wisblock RAK4631 Module pre-flashed with the Meshtastic firmware SoC – Nordic Semi nRF52840 Core – 32-bit Arm Cortex-M4F CPU @ 64 MHz Memory – 256 KB SRAM Storage – 1 MB Flash Wireless – Bluetooth LE LoRa Transceiver – Semtech […]

HackLED Pro LED controller – An Adafruit Sparkle Motion alternative with WS2812 and RGBCW LED support

HACK Lab HackLED Pro is an Adafruit Sparkle Motion-like LED controller that runs a custom version of WLED and supports both WS2812 and RGBCW LEDs, making it ideal for DIY lighting projects, smart home setups, and audio-reactive light displays. Built around an ESP32 MCU, this board includes 2-way WS2812 LED outputs, 5 PWM channels (RGBCW), and an onboard silicon microphone for music reactive LED setup. Like the Sparkle Motion, the outputs of this board are level-shifted, and there’s also a power switch that toggles the output power between 5V and 12V. The board features a USB-C port with a PD controller, with which you can power and program the board. The controller is housed in a thermally protected 3D printed case and is also compatible with the generic version of the WLED firmware. HackLED Pro specifications: Wireless module – ESP32-WROOM-32E-N4 WiFi and Bluetooth module with 4MB Flash LED Control 2x […]

$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born. RAwireless RAK11160 specifications: LPWAN SoC/SiP – STMicro STM32WLE5 Core – Arm Cortex-M4 MCU @ 48 MHz Memory – 64 KB RAM Storage – 256 KB flash memory with ECC Wireless  – Sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.4 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point-to-Point (P2P) communication Tx Power Output – […]

Mesh Mapper Remote ID Drone Mapping

Map Remote ID-enabled drones with ESP32-C3/S3 and Meshtastic LoRa modules

Colonel Panic’s Mesh Mapper is a project designed to map drones emitting the FAA’s Remote ID over WiFi or Bluetooth with location, altitude, pilot position, and identification data. This project utilizes an ESP32-C3 or ESP32-S3 to capture Remote ID transmissions within range, and then feeds the data into a Python Flask web application part of Mesh Mapper that provides real-time visualization and logging.  Meshtastic allows multiple detection nodes to share information across a mesh network, so several ESP32 nodes can be deployed in an area and be alerted when drones fly within your property or neighborhood. While you could use your own ESP32-C3/S3 board and Meshtastic hardware for this project, Colonel Panic designed a breakout board for XIAO ESP32C3 or ESP32S3 WiFi & Bluetooth module and Heltec LoRa 32 V3 connected over serial to make things easier. Something like the XIAO ESP32S3 for Meshtastic & LoRa devkit might also do, […]
