IP67-rated Helios SK51 CAN Keypad adds five programmable RGB tactile buttons to CAN Bus applications

Helios SK1 CAN Keyboard

Helios SK51 CAN Keypad is a waterproof (IP67-rated) keypad connected over CAN Bus with five tactile silicone buttons and LED backlighting. Each button is fully programmable and offers a 24-bit RGB color option. In some ways, it reminds me of the T-Keyboard-S3-Pro mechanical keypad, but instead of relying on USB, the SK51 CAN Keypad works over a CAN Bus compliant with the SAE J1939 standard, and it’s designed for more demanding environments. Helios SK51 specifications 5x programmable buttons with integrated display, each with a status LED on top. CAN protocols SAE J1939 compatible protocol Transmit – Button status on press/release or 1s interval Receive Simple Mode: Set backlight & status LED colors, brightness, and flash Full RGB: 24-bit RGB per LED (16.7 million colors) CAN Termination – Not Fitted USB – USB-C for firmware update Supply Voltage –  6 to 35 VDC Power Consumption – 5 to 200mA, depending on […]

ESP-HDMI-Bridge is an ESP32-P4 HDMI streaming adapter with USB, Ethernet, WiFi, and microSD card

ESP32-P4 MIPI HDMI adapter

ESP-HDMI-Bridge is an ESP32-P4-based HDMI streaming adapter based on Lontium Semiconductors’s LT8912B MIPI-DSI to HDMI bridge chip outputting MIPI-DSI video signal of ESP32-P4 to HDMI devices. It allows the user to connect a computer to an HDMI display or projector through USB, Ethernet, or WiFi, or use it directly as a digital signage player or live dashboard connected to an HDMI display. The current solution is based on the ESP32-P4-Function-EV-Board connected via its MIPI DSI connector to a 50x40mm board with the LT8912B bridge, a MIPI DSI input connector, LVDS and HDMI video outputs, and a 12-pin header with I2C, I2S audio, etc., with everything housed in a plastic enclosure. The best is to watch the video below, which shows various demos: USB to HDMI up to 720p30 or 1080p15 Ethernet to HDMI WiFi to HDMI up to 1080p40 using the ESP32-C6 2.4 GHz WiFi 6 module on the ESP-P4 […]

Xero MCU is a compact USB-C board based on STM32F411 microcontroller (Crowdfunding)

Xero MCU board

Xero MCU is a small STMicro STM32F411 Arm Cortex-M4F microcontroller board with a USB-C port, twenty through and castellated holes for GPIOs, a Debug connector, Reset and Boot buttons, and a few LEDs. The 100 MHz MCU embeds 512KB flash and 128KB SRAM, and the board is said to be designed for hobbyists, students, and professionals. For reference, the Xero MCU board features the same STM32F411CEU6 microcontroller found in the Black Bill board. However, it’s quite shorter at about half the size, and features castellated edges, making it suitable for soldering on a baseboard. Xero MCU specifications: Microcontroller – STMicro STM32F411CEU6 Arm Cortex-M4F MCU @ 100MHz with 512KB Flash, 128KB SRAM USB – 1x USB Type-C port for power and programming Expansion – 2x 20-pin through and castelled holes with up to 17x GPIO, I2C, 2x SPI, 2x UART, 4x ADC, 5V, 3.3V, and GND Debugging – 4-pin debug connector […]

JetKVM – A $69 KVM over IP solution with open-source software

JetKVM

We’ve been writing about some low-cost KVM over IP solutions like the Sipeed NanoKVM Cube or GL.iNet Comet in recent times, but the JetKVM has been pointed out to me as another alternative with the benefit of having open-source software (which the NanoKVM also got last month). The JetKVM was launched for $69 on Kickstarter last fall and the crowdfunding campaign was amazingly successful with over 4 million dollars raised from just over 30,000 backers.  Key features include 1080p60 video with 30-60ms latency using H.264 encoding, mouse and keyboard emulation, remote management via JetKVM Cloud using WebRTC for accessing the devices from outside the LAN, and open-source software written in Golang on Linux. JetKVM specifications: SoC – Rockchip RV1106G3 CPU – Arm Cortex A7 @ 1.0GHz VPU – H264 & H265 hardware encoder Memory  – 256 MB DDR3L on-chip Storage – 16 GB eMMC flash Display – 1.69-inch IPS capacitive […]

Haasoscope Pro open-source, real-time sampling USB oscilloscope supports up to 2GHz bandwidth (Crowdfunding)

Haasoscope Pro USB oscilloscope

The Haasoscope Pro is an open-source hardware, high-bandwidth, and real-time sampling USB oscilloscope. Building upon its predecessor, the Haasoscope, the new Pro model offers a bandwidth of 2GHz, 12-bit resolution, and a 3.2GS/s sampling rate. The Haasoscope Pro USB oscilloscope is “designed to be low cost, while maintaining super-fast performance.” While it only comes with 2 channels, the flexible design makes it possible to combine and sync multiple devices (using Cat5 cables) to double the sample rate or add more channels. The oscilloscope works with standard x10 passive probes but a custom active probe, the Haasoscope Pro-be, is also offered. It supports the full 2GHz analog bandwidth and is priced much cheaper than similar probes. The Haasoscope Pro USB oscilloscope’s high sampling rate and bandwidth make it ideal for radio frequency signal analysis and high-speed digital debugging. It is similar to the ThunderScope Thunderbolt and PCIe oscilloscope which offers more […]
