LimeNET Micro 2.0 Developer Edition board leverages Raspberry Pi CM4 and LimeSDR XTRX SDR module (Crowdfunding)

LimeNET Micro 2.0 developer edition

The LimeNET Micro 2.0 Developer Edition board is a modular software-defined radio (SDR) platform from Lime Microsystems that is based on the Raspberry Pi Compute Module 4 and the company’s own SDR board, the LimeSDR XTRX. It builds upon previous versions from Lime Microsystems, such as the LimeSDR Mini and LimeSDR Mini 2.0. It features a MIMO (multiple-input, multiple-output) radio and runs the more powerful Compute Module 4, an upgrade from the Raspberry Pi CM3 in earlier versions. The LimeSDR XTRX is an open-source, high-performance SDR in a compact, Mini PCIe form factor.  It provides a platform for building logic-intensive digital and RF designs and can be used for MIMO antenna configurations from 2Tx2R to 32Tx32R. The platform is built around a planar system board, the LimePSB RPCM, which integrates the CM4, the XTRX, and other components and interfaces to make a complete baseband + RF solution for diverse wireless […]

HealthyPi Move is an open-source nRF5340-powered biometric monitor worn like a watch (Crowdfunding)

HealthyPi Move

The HealthyPi Move is the latest biometric monitor in the HealthyPi series from ProtoCentral. It is the first to come in a wearable form factor and can measure up to eight vital signs. It is powered by a Nordic Semiconductor nRF5340 dual-core SoC, with a Cortex-M33 application processor and a Cortex-M33 network processor. It features 128MB of flash memory connected through a high-speed QSPI interface that can store up to 10 days of processed data. It is capable of measuring galvanic skin response (EDA/GSR), electrocardiogram (ECG) signals, and photoplethysmogram (PPG) signals for determining blood oxygen level (SPO2), blood pressure, and heart rate variability. It also includes a body temperature sensor and inertial measurement unit (IMU) with a 6-axis accelerometer and gyroscope. HealthyPi Move targets medical and biotech applications, including personal health tracking, building healthcare devices, and even clinical research with approval from the FDA or IRB. We have previously covered […]

Use your Nintendo Wii Nunchuk as a USB controller with ANAVI Handle open-source hardware adapter (Crowdfunding)

Wii Nunchuck USB port Raspberry Pi 4 retro gaming console

Leon ANAVI has launched another open-source hardware project with the ANAVI Handle that transforms the Nintendo Wii Nunchuck into a USB controller meaning the Wii controller can now be used with any common hardware such as computers, laptops, single board computers, retro-gaming consoles, and so on. The ANAVI Handle is built around the Seeed Studio XIAO RP2040 module based on Raspberry Pi RP2040 microcontroller and converts the Wii Nunchuck with a custom port carrying I2C signals into a standard USB HID device that works without any extra drivers. ANAVI Handle specifications: MCU module – XIAO RP2040 MCU – Raspberry Pi RP2040 dual-core Cortex-M0 processor at 133MHz and 264kB RAM. Storage – 2MB SPI flash USB – 1x USB type C port for power and data Misc – Reset button, boot button, some LEDs PCB Nunchuck connector with I2C signal Dimensions – 35.0 x 33.3 mm OSHWA certification – BG000134 ANAVI […]

Openterface Mini-KVM is an affordable KVM-over-USB device (Crowdfunding)

Openinterface Mini-KVM

Openterface Mini-KVM compact, open-source hardware KVM-over-USB device with HDMI and audio inputs which connects over a USB-C port to the host computer. We’ve seen quite a few low-cost KVM-over-IP solutions based on single board computers over the years, but the Openterface Mini-KVM is quite different (and cheaper) as a plug-and-play and network-independent KVM-over-USB device that establishes a direct HDMI and USB connection between the host computer and the target device. It supports many of the same features as KVM-over-IP solutions except for some features such as ATX support found in the PiKVM v4 Plus or the Pi-Cast KVM with an expansion board that allows the target device to be turned off and from the host device. Mini-KVM (model LIG03D01) specifications: Control method – KVM-over-USB Video capture – Up to 1920×1080 @ 30 Hz with under 140ms latency through HDMI or VGA (the latter requires an add-on VGA-to-HDMI cable) Audio capture […]

Sonocotta’s ESParagus “Media Center” is a series of ESP32-based, open-source audio streamers (Crowdfunding)

Louder ESParagus

ESParagus Media Center is a line of audio streamers from Sonocotta, all powered by an ESP32 microcontroller module. It includes the ESParagus HiFi MediaLink, Loud ESParagus, and the Louder ESParagus. The ESP32-based audio centers can be used to power old stereo speaker systems that lack streaming capabilities. They are completely open-source, consume little power when not in use, and boot up in seconds. The ESParagus Media Center products are based on the ESP32-WROVER microcontroller module with Wi-Fi and Bluetooth connectivity and an onboard PSRAM chip. They are fitted with an external Wi-Fi antenna and the top-end model – the Louder ESParagus – is fitted with a W5500 LAN chip for Ethernet networking. All three ESParagus Media Centers run squeezelite-esp32 firmware which supports Spotify Connect, Apple AirPlay, and Logitech Media Server. Integrations with Home Assistant are possible and can be useful for multi-room configurations. The Louder ESParagus is quite similar to […]

ESP32-C6-Bug WiFi 6, Bluetooth LE, and 802.15.4 board takes a PoE Ethernet shield (Crowdfunding)

ESP32-C6 PoE board

We’ve already covered a range of ESP32-C6 boards, but none supporting Ethernet and PoE so far, and the ESP32-C6-Bug board brings that to the table thanks to the Esp32-Bug-Eth shield with a W5500 Ethernet chip, an RJ45 jack and a PoE power module. Like other ESP32-C6 devices, the little board supports Wi-Fi 6, Bluetooth LE 5, as well as Thread and Zigbee through its 802.15.4 radio, but it also integrates some other interesting features such as castellated holes for easy soldering on a carrier board and support for LiPo batteries with built-in battery charging and protection circuits. ESP32-C6-Bug board specifications: SoC – ESP32-C6FH4 MCU cores 32-bit RISC-V core @ 160 MHz 32-bit RISC-V core @ 20 MHz low-power coprocessor can run tasks even when the main system is in deep sleep state Memory – 512 KB SRAM Storage – 4 MB Flash Wireless – WiFi 6, Bluetooth LE 5, and […]
