ALFA Network HaLow-U – An 802.11ah WiFi HaLow USB adapter supporting AP and STA mode

WiFi HaLow USB adapter

ALFA Network HaLow-U is an 802.11ah WiFi HaLow USB adapter based on the Newracom NRC7292 chipset and NXP i.MX 6 processor that works both in access point (AP) and client (STA) modes. It delivers long-range WiFi up to one kilometer in the 900 MHz frequency ISM bands and is mostly useful for IP cameras and high-end sensors. The ecosystem around WiFi HaLow (802.11ah) is expanding slowly, but surely, and we previously covered a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras, and also ALFA Network’s AHPI7292S Raspberry Pi HAT that found its way into RAKWireless WisGate Connect gateway. The new HaLow-U USB adapter adds another way to bring WiFi HaLow connectivity to more devices. HaLow-U specifications: SoC – NXP i.MX6 Arm Cortex-A9 processor System Memory – 256MB DDR3 Storage – 32MB NOR flash Connectivity 802.11ah HaLow Newracom NRC7292 chipset […]

Coin cell-powered boards provide an easy way to test USB-C cables

C2C caberQU USB-C Cable Tester

The A2C caberQU and C2C caberQU boards enable the quick and easy testing of respectively USB-A to USB-C and USB-C to USB-C cables without external hardware. Powered by a CR2032 coin cell battery, the boards apply a voltage to all pins of a cable and measure which ones are connected to the other end. The results can be visualized immediately through various LEDS on the board. The C2C caberQU board comes with a dedicated LED for each of the 24 USB pins and the shield, and it’s possible to test the USB Type-C to USB Type-C cable in several different modes: USB 2.0/1.1 USB Power Delivery USB 3.0/3.1/3.2 Alternate Mode Debug Accessory Mode Audio Adapter Accessory Mode The A2C caberQU board has fewer pins and LEDS for testing USB-A to USB-C cables specifically, but it works the same way.

Chart confirms higher level of Raspberry Pi restocks

Raspberry Pi Restocks

Earlier this month, we noted that Raspberry Pi supplies were improving mostly from tweets from Eben Upton who provided data about shipped boards since the beginning of the year. But there are also third-party data that confirm this since RPILocator provides statistics for restocks of Raspberry Pi hardware from approved resellers. The chart below shows weekly data of restocks since January 2022 until today, and we can clearly see a jump in restocks in recent weeks, especially for the Raspberry Pi 4, so there’s no need to steal old boards from discarded scooters anymore 😉 The ramp-up really started on week 25 (June 19-25) and peaked on week 28 (July 10-16) possibly to fill back orders, and restocks have been going down in recent weeks but still at a higher level than previously. While the improvement is mostly visible for the Pi 4, the Raspberry Pi 3 and Raspberry Pi […]
