XCVR LoRa-based IoT development board & reference design features SX1261, SX1262, or LLCC68 chip

XCVR LoRa based IoT development board

Semtech Corporation and “Connected Development” engineering firm have launched the XCVR development board and reference design based on Sentech SX1261, SX1262, or LLCC68 transceivers with the last one targeting Smart Home applications. The XCVR development board is actually an Arduino shield that’s been tested with Nordic nRF52840-DK board, but should work with most boards equipped with Arduino Uno headers. It can be used for the design of LPWAN IoT applications using SX1262x transceivers such as smart meters, industrial controllers, asset tracking, building automation, smart agriculture, etc… while the LLCC68 model is more useful for Smart Home applications and consumer devices. XCVR shield specifications and features: LoRa and FSK Modem Programmable bit rate up to 62.5 kbps LoRa and 300 kbps FSK External antenna Link budget 163 dB maximum for SX1261 170 dB maximum for SX1262 configurations. Tx Power +15 dBm high-efficiency PA for SX1261 +22 dBm or +15 dBm high-efficiency […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.3 release

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]

100ASK-V853-Pro – A feature-rich Allwinner V853 board designed for AI vision applications

100ASK V853 Pro

The 100ASK-V853-Pro board is a development kit consisting of an Allwinner V853 system-on-module board (SoM) and a feature-rich carrier board with a large number of interfaces. Allwinner V853 supports up to 1TOPS of NPU computing power and is mainly for AI vision application development. The core board contains a DDR and eMMC as well as a PMU chip (AXP2101) and is connected to the carrier board through a board-to-board connector. All the functional resources of the V853 are drawn out through the carrier board. The carrier board comes with 2-channels CSI camera interfaces as well as RGB and MIPI DSI display interfaces.

Using Pico:ed V2 board as a replacement for BBC Micro:bit

Pico:ed V2 BBC Micro:bit Alternative

We’ve received a sample of the Pico:ed V2 board developed by ELECFREAKS and will show how to use it as a replacement for the BBC micro:bit in a project using CircuitPython. We’ve already covered the board in detail with specifications, block diagram, and pinout diagram before, and it’s basically a Raspberry Pi Pico RP2040 board with BBC Micro:bit form factor including a 17×7 Dot Matrix LED display, some buttons, a buzzer, but no wireless connectivity, relying only on USB instead. CircuitPython firmware installation on the Pico:ed V2 board The board supports C/C++, MicroPython, and CircuitPython programming languages, and for this review, we’ve decided to download the CircuitPython UF2 firmware. Press and hold the BOOTSEL button after having downloaded the firmware file… … and connect the board to your computer using a USB cable before releasing the BOOSEL button on the Pico:ed V2 board, which should then show up as the […]
