SlimeVR is a set of open hardware sensors and open source software that facilitates full-body tracking (FBT) in virtual reality. Without the need for a base station, SlimeVR makes wireless VR FBT affordable and comfortable. SlimeVR FBT provides simple, effective body and limb tracking in VR games and other applications. It utilizes high-quality inertial measurement unit (IMU) sensors and a Wi-Fi connection to a PC instead of wires, cameras or base stations to make full-body tracking comfortable and affordable. Take the lower-body suit, for example, where five trackers—one on each thigh, one on each ankle, and one on the waist—are enough to get the job done. Each tracker monitors its own rotation in space, and the SlimeVR software uses your scale and headset position to calculate joint angles and estimate limb position. In more technical terms, SlimeVR relies on absolute orientation sensors, a configurable skeleton model, and forward kinematics. The result is like having virtual Vive trackers installed at strategic locations on your body.
The portable soldering iron launched by PINE64 in the early days was based on the GD32 design. This time it was upgraded to the second generation product, which was changed to the domestically produced BL706. Its feature is that it supports low-power Bluetooth. The Bluetooth OTA upgrade function will be added to IronOS later. IronOS supports a variety of portable DC, QC, and PD powered soldering irons, and supports all standard functions of smart soldering irons.

Dynamic NFC tag expansion board for STM32 Nucleo, based on M24LR
EVB-LIV3FL is a complete standalone evaluation platform for Teseo-LIV3FL low power GNSS module ST solution.
The add-on kit for the NTAG I²C+ Explorer Kit (Interconnected NFC Tag) contains Category 4, Category 5 and Category 6 Flex antennas.
Loko is an open source, battery-operated GPS tracker. It's a small, simple, and useful device that sends navigation data to its receiver via a peer-to-peer LoRa radio. Unlike other similar technologies, there are no ongoing costs. Loko is based on radio communication and requires no SIM card/monthly fee. It also works everywhere, even without 2G/3G/LTE coverage.
ST25DV04K Dual Interface EEPROM 14 mm x 14 mm Dual Layer Antenna Reference Board
CaribouLite is an affordable open source dual-channel software-defined radio (SDR) platform and an SDR-focused FPGA development framework implemented as a Raspberry Pi (RPi) HAT. CaribouLite turns your Raspberry Pi single-board computer (SBC) into a standalone dual-channel radio Tx/Rx with a tunable spectrum up to 6 GHz. CaribouLite gives you complete control over its hardware, including FPGA, firmware, and all supporting software. With the deeply integrated IceStorm toolchain, writing your own FPGA applications couldn't be easier. You can reuse many Verilog modules, such as the SPI and SMI modules, to support custom applications for CaribouLite hardware.
