TLDR
-
BYOMesh combines SX1276 sub-1GHz and SX1281 2.4GHz LoRa on one tiny companion dev kit, targeting mesh backhaul with up to 100x more bandwidth.
Key Takeaways
-
Dual-chip design: SX1276 covers the full sub-1GHz ISM band; SX1281 adds high-speed 2.4GHz LoRa on a single small board.
-
2.4GHz LoRa targets long mountain-to-mountain backhaul links (e.g. PNW) without stepping up to WiFi, WiFi HaLow, or licensed spectrum.
-
Compatible with Meshtastic, MeshCore, MeshTNC, and Reticulum, covering the major open mesh stacks.
-
HaLow comparison from source discussion: 2.4GHz LoRa is roughly 30 KB/s vs. HaLow’s ~40 MB/s, so range wins but throughput still trails.
-
Payload aggregation over point-to-point 2.4GHz links is flagged as a promising pattern to reduce collision risk on RF.
Hacker News Comment Review
-
One comment focused on sending photos over Meshtastic, signaling interest in higher-throughput use cases that BYOMesh’s 2.4GHz tier could address.
-
No broader technical debate yet on antenna design, power draw, or real-world link budgets at 2.4GHz LoRa ranges.
Notable Comments
-
@codensolder: raises photo transfer on Meshtastic as a concrete driver for higher-bandwidth LoRa.
