ESP32 Bus Pirate open-source firmware works on off-the-shelf hardware

ESP32 Bus Pirate

ESP32 Bus Pirate is an open-source firmware inspired by the original Bus Pirate from Dangerous Prototypes, which turns off-the-shelf (ESP32-S3) hardware into a multi-protocol hacker’s tool. It supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI. It’s been tested on Espressif ESP32-S3-DevKitC-1 development board, M5Stack Cardputer, M5StickC Plus2, Atom S3 Lite, M5Stamp S3, and LILYGO T-Embed (CC1101) boards. ESP32 Bus Pirate firmware highlights: Interactive CLI via USB serial – For faster performance and high responsiveness Web interface (over WiFi) – No cable needed to the host, works from any web browser Supported Modes HiZ (default) – High-Z is a safe mode where all outputs are disabled and all power supplies are turned off I2C (scan, glitch, slave mode, dump) SPI (flash, SD card, slave mode) UART / Half-Duplex UART (bridge, read, write) 1-WIRE (ibutton, temp sensor) 2-WIRE […]

MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging

MeshCore LoRa off-grid messaging

While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet. The project’s GitHub repository provides some high-level differences compared to the Meshtastic and Reticulum projects: MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable. MeshCore key features: Multi-hop […]

ESP32-S3 board with AM/FM radio

LILYGO T-Embed SI4732 is an ESP32-S3 development board with an AM/FM radio, a TFT display, a rotary encoder, a built-in microphone, and a microSD card slot powered through a USB-C port or LiPo battery. As its name implies, it’s based on the earlier LILYGO T-Embed battery-powered WiFi and BLE controller with a display and rotary encoder, but also adds a Skyworks SI4732 AM//FM/SW/LW radio receiver to the mix. LILYGO T-Embed SI4732 specifications: Wireless module – ESP32-S3-WROOM-1 module SoC – ESP32-S3 CPU – Dual-core Xtensa LX7 processor @ 240 MHz  with vector extension for AI/ML Memory – 512 KB SRAM, 8 MB PSRAM Storage – 16MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE PCB antenna Storage – MicroSD card slot Display – 1.9-inch IPS color TFT LCD with 320 x 170 resolution (ST7789V SPI driver) Audio – 2x microphones, 8 Ohm @ 1W speaker Radio – Skyworth […]

LILYGO MySondy GO LoRa32 board tracks radiosondes (weather balloons) with a 433MHz LoRa module

LILYGO MySondy GO

“LILYGO MySondy GO LoRa32” is a small ESP32-PICO-D4 board with a 433 MHz LoRa module and a 0.96-inch OLED designed to track (RS41) radiosondes, which are units attached to weather balloons used to collect meteorological data like temperature, humidity, and atmospheric pressure. It looks to be an older TTGO T3 board with a 433 MHz LoRa32 module from the company preloaded with the MySondo firmware that allows hobbyists in the amateur radio and weather enthusiast communities to track weather balloons and potentially recover them. LILYGO MySondy GO LoRa32 specifications: SiP – Espressif Systems ESP32-PICO-D4 system-in-package with ESP32 dual-core Xtensa processor @ 240 MHz, 2.4GHz Wi-Fi and Bluetooth 4.2 dual-mode, 4MB flash LoRa module – LORA32 RF Transceiver – Semtech SX1268 connected over SPI to the ESP32 SiP Frequency – 433 MHz (The T3 board has options for 868 and 915 MHz, which I suspect are not suitable for radiosondes) Tx […]
