Giveaway Week 2023 – Elecrow ESP32 Terminal with a 3.5-inch touchscreen display and OV2640 camera

Elecrow ESP32 Terminal giveaway

If I remember correctly, Elecrow sent me an end-of-year gift with a notebook (paper style), a pen, and a 3.5-inch ESP32 terminal. I had completely forgotten about it, and while wondering what I would give for Giveaway Week 2023, and looking around in drawers and on shelves, I found an “ESP32 Terminal” package, and I was like “What the F is that and where is it coming from?”. Long story short, the 6th prize of this year’s giveaway week is Elecrow’s ESP32 Terminal with a 3.5-inch touchscreen display that also comes with a front-facing OV2640 camera and six Crowtail connectors for expansion plus a LiPo battery connector. Elecrow ESP32 terminal specifications: Wireless module – ESP32-S3 2.4 GHz Wi-Fi and Bluetooth 5 (LE) module with 16MB flash and 8MB PSRAM Storage – MicroSD card slot Display – 3.5-inch TFT LCD display with 480×320 resolution (ILI9488 driver), capacitive touchscreen Camera – 2MP […]

Giveaway Week 2023 – TBS7901 mini PCIe DVB-S2X/S2 module

TBS7901 mini PCIe DVB- S2X/S2 module giveaway

The second prize of Giveaway Week 2023 is a TBS7901 mini PCIe DVB-S2X/S2 module designed to be connected to a PC or board with a mini PCIe socket in order to watch, record, or broadcast free-to-air video received from a satellite dish. I received both M.2 and mPCIe DVB-S2X modules last August, but I haven’t had time to test any of those yet. So I’m keeping the M.2 module for my own testing once time permits and will be giving away the mini PCIe module to one of CNX Software readers. The module comes with a coaxial antenna cable, as well as a TBS-7901PW power board and SATA power cable since DVB-S/S2/S2X satellite TV requires 13V and 18V DC as well which will be outputted won’t the power board using the 12V from a PSU. You’ll probably need a Windows machine too since TBS provides Windows drivers for the TBS7901 […]

$150 BeagleV-Fire SBC features Microchip PolarFire RISC-V SoC FPGA, supports BeagleBone capes

BeagleV-Fire SBC

BeagleV-Fire is a new single board computer powered by Microchip PolarFire MPFS025T penta-core RISC-V SoC FPGA that follows the BeagleBone Black form factor for compatibility with BeagleBone capes expansion boards. Microchip PolarFire RISC-V SoC FPGA was one of the first Linux-compatible RISC-V SoCs and was found in pricey boards such as the Icicle and TySOM-M-MPFS250 development boards. I also got an Icicle board for review, and while getting started with the Yocto Linux BSP was OK, I really struggled with the FPGA part including just installing Libero SoC in Ubuntu and going through the license, and even I gave up trying to run a bitstream sample on the board due to a lack of time. The BeagleV-Fire makes it much cheaper to try out the PolarFire and hopefully makes it easier to get started with both Linux and the FPGA fabric through easier-to-understand documentation and code samples. BeagleFire-V specifications: SoC […]
