A LoRa-based Walkie-Talkie? Meet LILYGO T3-S3 MVSR LoRa voice communication kit

LoRa Voice Communication Kit Walkie Talkie

With its low-power, long-range capabilities, LoRa has been used for P2P and Mesh messaging with firmware like MeshTastic, but due to its limited bandwidth, we haven’t seen quite as many LoRa audio applications. This has not stopped LILYGO from designing the T3-S3 MVSR LoRa voice communication kit, integrating LoRa radio, a microphone, and a speaker to use the board as a walkie-talkie solution working over Semtech SX1262 or SX1280 RF transceiver. LILYGO T3-S3 MVSR specifications: SoC – Espressif Systems ESP32-S3FH4R2 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz Wireless – 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 2MB PSRAM Storage – 4MB SPI flash Storage – MicroSD card slot Display – 0.96-inch 128×64 OLED display with SSD1306 I2C driver Audio MAX98357A Speaker MSM261S4030HOR Microphone LoRa module (one or the other) LORA32 SX1262 with 868MHz or 915 MHz radio LoRa 2.4G module based […]

Radxa CM3J industrial-grade Rockchip RK3568J SoM is compatible with Raspberry Pi Compute Module 4

Radxa CM3J is a Raspberry Pi Compute Module 4 compatible SoM powered by a Rockchip RK3568J industrial-grade quad-core Cortex-A55 SoC and equipped with up to 8GB LPDDR4x and up to 256GB eMMC flash. It’s an update to the Radxa CM3 based on the Rockchip RK3566 SoC with an industrial temperature range and only two board-to-board connectors, and can also be viewed as a cost-down version of the Radxa CM3i with RK3568 and four B2B connectors. It competes directly against the industrial-grade Raspberry Pi Compute Module 4 introduced at the beginning of this month. Radxa CM3J specifications compared to the Radxa CM3 and Raspberry Pi CM4: The Radxa CM3J has been tested with the official Raspberry Pi CM4 IO Board, WaveShare CM4‑POE‑UPS‑BASE, WaveShare CM4‑IO‑BASE‑B, and WaveShare CM4‑NANO‑B, but other carrier boards for the Compute Module 4 may also be supported. Like with other such modules, there’s no 100% pin compatibility with […]

Linux 6.14 release – Main changes, Arm, RISC-V, and MIPS architecture

Linus Torvalds has just announced the release of Linux 6.14 on LKML: So it’s early Monday morning (well – early for me, I’m not really a morning person), and I’d love to have some good excuse for why I didn’t do the 6.14 release yesterday on my regular Sunday afternoon release schedule. I’d like to say that some important last-minute thing came up and delayed things. But no. It’s just pure incompetence. Because absolutely nothing last-minute happened yesterday, and I was just clearing up some unrelated things in order to be ready for the merge window. And in the process just entirely forgot to actually ever cut the release. D’oh. So yes, a little delayed for no good reason at all, and obviously that means that the merge window has opened. No rest for the wicked (or the incompetent). Below is the shortlog for the last week. It’s nice and […]
