KrakenRF, the team behind the KrakenSDR, has designed the Discovery Drive ESP32-S3-based, low-cost, fully weatherproof, automatic azimuth/elevation (Az/El) antenna rotator for their Discovery Dish or other directional antennas, such as Yagis and Wi-Fi grids, weighing up to 5kg. Compared to DIY projects like SatNOGS (which require 3D printing and hardware sourcing), the Discovery Drive is designed as a plug-and-play solution. You can simply mount it to a mast, attach the dish, connect to 12V power and Wi-Fi, and use its web UI to start tracking polar-orbiting weather satellites (like METEOR-M2 or FENGYUN), CubeSats, or amateur radio satellites. KrakenRF Discovery Drive specifications: Controller – Espressif Systems ESP32-S3-based control board Connectivity – 2.4 GHz 802.11 b/g/n Wi-Fi 4 (via ESP32) with external antenna Motor and Rotation Torque – Up to 125 kg·cm (12.25 Nm); supports antenna payloads up to 5 kg Azimuth Range – -360° to +360° Elevation Range – 0° to […]

STMicroelectronics ST64UWB Arm Cortex-M85 ultra-wideband (UWB) SoC family supports both the current IEEE 802.15.4z and the upcoming IEEE 802.15.4ab UWB standards for longer-range, more reliable positioning and secure proximity-based interactions. It mainly targets digital car keys, hands-free access, and smart-device detection. The family includes the ST64UWB-A100 (automotive entry), ST64UWB-A500 (automotive premium), and ST64UWB-C100 (industrial/smart home), all built on an 18 nm FD-SOI process that improves the RF link budget by ~3 dB, yielding roughly 50% additional range beyond what IEEE 802.15.4ab alone provides. The automotive-focused A-series offers ASIL-A(B) safety support, while the ST64UWB-C100 targets consumer and commercial applications. ST64UWB family specifications: MCU Core 32-bit Arm Cortex-M85 CPU with DP-FPU, MVE, and ETM Frequency Up to 100 MHz (ST64UWB-C100, ST64UWB-A100) Up to 256 MHz (ST64UWB-A500) Memory/Storage Integrated PCM Memory SRAM and Back-up SRAM Wireless Connectivity Ultra-wideband (UWB) Radio IEEE 802.15.4z-2020 and IEEE 802.15.4ab support UWB channels 5, 6, 8, 9, 10, […]
