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

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 […]

W6300-EVB-Pico2 board combines RP2350 MCU with WIZnet W6300 QSPI Ethernet controller for 80+ Mbps data rate

W6300-EVB-PICO2 board with Raspberry Pi RP23500 and W6300 QSPI Ethernet controller

WIZnet W6300-EVB-Pico2 is a development board that combines a Raspberry Pi RP2350 MCU with the company’s new W6300 QSPI Ethernet controller capable of 80+ Mbps data rates. WIZNet has made several 10/100Mbps Ethernet controllers over the years that connect to microcontrollers via SPI, but the speed is often limited to 15 to 70 Mbps due to a low SPI clock frequency and small buffers. The WIZNet W6300 Ethernet controller can deliver higher speed thanks to a 150MHz system clock, a QSPI interface with four data lines, 64KB SRAM, and 4KB TX/RX buffer for each of the 8 sockets. W6300 QSPI Ethernet controller W6300 features and specifications: Host Interface – High-speed QSPI (MODE 0/3), system bus with 2 address signals & 8-bit data Internal 32KB SRAM for Tx/ Rx buffers (64KB in total) 8x independent sockets with 64KB Memory 10BaseT / 10BaseTe / 100BaseTX Ethernet PHY Integrated Auto negotiation (Full and […]

Youyeetoo X1 x86 SBC Review – Part 2: GPIO, UART, I2C, SPI, NFC, PoE module, and power consumption

The Youyeetoo X1 x86 single board computer (SBC) with an Intel Celeron N5105 Jasper Lake CPU differs from a typical Intel or AMD mini PC by its range of IOs including SPI, I2C, UART, NFC connectivity, and support for PoE module that you won’t find in a typical computer, and that’s what we will test in the second part of the X1 SBC review along with power consumption. The Youyeetoo X1 SBC is also different from Arm-based single board computers since we can just install any x86-compatible operating system by ourselves, and w don’t need to flash a board-specific image like we would do with Arm SBCs and peripherals such as SPI, I2C or UART may be or may not usable immediately due to lack of supported drivers. We’ve already installed Ubuntu 22.04 on the Youyeetoo X1 in the first part of the review, so in the second part, we’ll […]
