Morse Micro MM6104, MM6108 Wi-Fi HaLow SoCs support up to 32.5 Mbps data rate

Australian company Morse Micro MM6104 and MM6108 Wi-Fi HaLow SoCs should offer some competition to the Newracom NRC chips found in all 802.11ah WiFi HaLow boards and devices released so far. Both MM610x chips have similar features, but the MM6104 SoC supports 1/2/4 MHz channel bandwidth for up to 15 Mbps data rate – just like the Newracom NRC7292 chip – while the more powerful MM6108 can handle a data rate of up to 32.5 Mbps thanks to 1/2/4/8 MHz channel bandwidth. MM6104/MM6108 specifications: Optional 32-bit RISC-V Host Applications Processor (HAP) Single-Chip IEEE802.11ah Wi-Fi HaLow transceiver for low-power, long-reach IoT applications Worldwide Sub-1 GHz frequency bands (850MHz to 950MHz) On-chip power amplifier with support for external PA option MM6104 – 1/2/4 MHz channel bandwidth for up to 15 Mbps data rate (Note: the datasheet reads “single-stream max data rate up to 40 Mbps”, but it appears to be a mistake […]

Add WiFi HaLow to Raspberry Pi with ALFA Network AHPI7292S HAT

ALFA Network AHPI7292S is a Raspberry Pi HAT with WiFi HaLow (802.11ah) offering low power connectivity, up to one kilometer line-of-sight range, and that’s mostly useful for security cameras, but it can also be used to extend the range of the network for other purposes. The Newracom NRC7292 expansion board adds to be few WiFi HaLow hardware we’ve seen in the past year including a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras. ALFA Network AHPI7292S specifications: Chipsets – Newracom NRC7292 WiFi HaLow SoC (IEEE 802.11ah draft 8.0 compliant) RF – Qorvo RFFM6901 front-end Frequencies – 847 MHz (TW), 866 MHz (EU), 915 MHz (US), 922 MHz (KR), 924 MHz (JP) Modulation – OFDM with BPSK, QPSK, 16QAM, 64QAM Data rate – 150 Kbps ~ 15 Mbps Channel bandwidth – 1/2/4 MHz Antenna connector – 1x IPEX/U.FL connector or […]

PiSquare enables wireless Raspberry Pi HAT control though ESP8266 and RP2040 MCUs (Crowdfunding)

PiSquare Wireless Raspberry Pi HAT RP2040 & ESP8266

SB Components PiSquare is a board following the Raspberry Pi HAT form factor, and based on Raspberry Pi RP2040 microcontroller & ESP-12E Wireless module in order to control multiple Raspberry Pi HATs wirelessly without stacking them on their Raspberry Pi. The PiSquare uses Socket programming to control multiple Raspberry Pi HATs wirelessly, and for instance, you could connect multiple HATs with SPI or UART without the expansion boards conflicting with each other since the physical interface is handled by the Raspberry Pi RP2040 on each PiSquare connected over WiFi (ESP8266) to the Raspberry Pi SBC. PiSquare hardware specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz Storage – 16Mbit SPI flash Display – 0.91-inch OLED display Connectivity – 802.11b/g/n WiFi 4 via ESP-12 (ESP8266) module USB – 1x USB Type-C port 40-pin header and form factor compatible with the official Raspberry Pi HATs Power Supply […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]
