Firmware Collection

Below includes recommended firmware versions for different models and naming conventions

Naming Convention

1. 130 firmware: v0.2
2. Early firmware: Uses date format, e.g. Firmware 3-14 means released on March 14, 2025
3. Naming rule modified in May 2025: BMCU version + major version + test sequence number (optional). Stable versions omit the sequence number. Example: BMCU-C-V0.1-0013 Test means for BMCU-C, V0.1 version, 13th test version. Note: When major version changes, the test sequence number continues incrementing without reset.

Firmware for 130 Version

Recommended to use v0.2 stable version. Due to its early stage, our collection is incomplete and only v0.2 (stable) is recommended.

Firmware for BMCU-B (Steel Ball)/Early 370 Version

Popular version is 3-14. This version improves performance and reduces (but doesn't completely eliminate) the "five-way burst" issue. If the five-way is already weakened, bursting may still occur.

Firmware for BMCU-C (Hall Effect)

BMCU-C is under active development. This content was written on May 26, 2025 - please check timeliness.

As of now, the latest test firmware is BMCU-C-V0.1-0013 Test, which has been tested working well on A1.

Other popular versions:

• 4-23-2 recommended for A1
• 4-23-3 recommended for P/X series

The difference is that -3 version has more aggressive feeding and may cause noticeable impact noise on A1.
