Bus Pirate 5XL and 6 hardware debugging tools utilize Raspberry Pi RP2350A and RP2350B microcontrollers

Dangerous Prototypes Bus Pirate

The Bus Pirate 5XL and 6 are open-source hardware debugging tools respectively based on Raspberry Pi RP2350A and RP2350B and designed to simplify interaction with various bus protocols like 1-Wire, I2C, SPI, UART, several LEDs, and more. The idea is to send commands to a chip or sensor and get the response, without writing a single line of code making it ideal for hardware hacking and tinkering. The devices feature buffered I/O pins with voltage and current measurement, a programmable power supply with current limiting, an RGB LCD  for pin status and info, and an auxiliary header for connecting logic analyzers. All these features make this device useful for applications like debugging circuits, prototyping projects, and reverse engineering devices. The new devices are updates to the Bus Pirate 5 based on Raspberry Pi RP2040 MCU. You’ll find Bus Pirate specifications for the three models in the table below. The original […]

Firefly EC-R3576PC FD is an Embedded Large-Model Computer based on Rockchip RK3576 processor

Firefly RK3576 Embedded Large Model Computer

Firefly EC-R3576PC FD is described as an “Embedded Large-Model Computer” powered by a Rockchip RK3576 octa-core Cortex-A72/A53 processor with a 6 TOPS NPU and supporting large language models (LLMs) such as Gemma-2B, LlaMa2-7B, ChatGLM3-6B, or Qwen1.5-1.8B. It looks to be based on the ROC-RK3576-PC SBC we covered a few weeks ago, and also designed for LLM. But the EC-R3576PC FD is a turnkey solution that will work out of the box and should deliver decent performance now that the RKLLM toolkit has been released with NPU acceleration. However, note there are some caveats doing that on RK3576 instead of RK3588 that we’ll discuss below. Firefly EC-R3576PC FD specifications: SoC – Rockchip RK3576 CPU 4x Cortex-A72 cores at 2.2GHz, four Cortex-A53 cores at 1.8GHz Arm Cortex-M0 MCU at 400MHz GPU – ARM Mali-G52 MC3 GPU clocked at 1GHz with support for OpenGL ES 1.1, 2.0, and 3.2, OpenCL up to 2.0, and […]

A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface

Raspberry Pi RP2530 HSTX interface

The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython. The high-speed serial transmit (HSTX) interface is detailed in the RP2350 datasheet starting on page 1118 where it reads “The high-speed serial transmit (HSTX) interface streams data from the system clock domain to up to 8 GPIOs at a rate independent of the system clock”. Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I […]

Twotrees SK1 3D printer review – Part 2: Enclosure kit and AI camera

Twotrees SK1 Enclosure Kit AI camera review

We reviewed the Twotrees SK1 CoreXY 3D printer capable of delivering high printing speeds last March, but here’s a second part of the review as the company sent us additional accessories namely the enclosure kit For SK1 and the AI camera for SK1 which we will report on today. The main structure of the enclosure is made of metal sheets plus a door that opens from the front and a top plate made of tempered glass. The SK1 3D printer enclosure makes the 3D printer more beautiful, protects it from dust, is easy to install, and features a fan and air filter system. It’s also designed to mount the AI Camera for SK1 to help users monitor the SK1 while printing is in progress. TwoTrees Enclosure Case Kit For SK1 The interior of the Twotrees SK1 3D printer enclosure is mostly made of metal and includes a tempered glass door […]
