Pi-Cast is a portable KVM switch based on Raspberry Pi CM4 (Crowdfunding)

Pi-Cast with HAT

The Pi-Cast KVM is a compact, open-source KVM (Keyboard, Video, Mouse) over IP device based on the Raspberry Pi CM4. It is powered by PiKVM, an open-source IP-KVM solution, and allows you to control and manage other devices remotely regardless of the operating system or even if one isn’t installed. The Pi-Cast KVM is capable of controlling any device with HDMI and USB ports. It works for low-level access and enables BIOS and UEFI configuration without an operating system installed. You can turn off and start the target system, as well as check for low-level hardware problems, all from a web browser. The Pi-Cast KVM is similar to the PiKVM v3 but is built around the Raspberry Pi CM4 (like the PiKVM v4) instead of being a HAT for Raspberry Pi SBC. The company behind this device has compared the Pi-Cast with market alternatives such as PiKVM v4 Plus and […]

Ollie v2 USB to UART/CAN/RS485/RS232 converter gets USB-C port, plastic enclosure, and more (Crowdfunding)

USB-C to UART, CAN Bus, RS485, and RS232 converter

Ollie v2 is an improved version of the Ollie USB to isolated UART, CAN Bus, RS232, and RS485 converter that gains a USB-C port, a plastic case, the ability to set the voltage from the target board, and various other minor improvements. Like the first version, the Ollie v2 is a portable tool designed for hackers and field engineers that allows them to work with a single device instead of a bunch of USB converters, each handling a single protocol, and isolation makes sure the host, such as a laptop, is protected from high voltages. Ollie V2 specifications: Serial chip – WCH CH344 quad-serial port chip (instead of XR21V1414 in the first design) Host interface – USB Type-C port Isolated interfaces (all with ESD protection) 2x UART ports up to 6 Mbps with 1.8/3.3/5 V or target voltage levels (set by slide switch) CAN 2.0A/B up to 1 Mbps bus […]

AI in a box offline LLM solution leverages Rockchip RK3588S’ NPU (Crowdfunding)

offline open source LLM Radxa Rock 5A
