Downloads
Every MBC library, block extension, example pack and catalog on one page. Check the version and the firmware it matches first: products shipped from October 2026 run protocol v2 firmware, and files marked "legacy" only work with firmware shipped before 2026-10.
Tip
Not sure which firmware your sensor has? Run the product's
01_helloArduino example, or use the "protocol version" block in mBlock / micro:bit: 2 means new firmware.

| File | Status | Notes |
|---|---|---|
| MBC_Pro_Sensors_mBlock5_v2.2.0_import.mext | In development: import it yourself (advanced) | v2.2.0 = all v2.1.0 blocks + 15 SharpShot Vision object-detection blocks (132 in total); the category is renamed "SharpShot Vision" and the School / WRO edition categories "SharpShot Vision (legacy)" (for the SharpShot Vision; its mBlock edition is not yet hardware-verified). Import it the same way as the v2.0.0 row |
| MBC_Pro_Sensors_mBlock5_v2.1.0_import.mext | In development: import it yourself (advanced) | v2.1.0 = all v2.0.0 blocks + a "Vision Universal" category of 22 blocks (for the SharpShot Vision; its mBlock edition is not yet hardware-verified). Import it the same way as the next row |
| MBC_Pro_Sensors_mBlock5_v2.0.0_import.mext | In development: import it yourself (advanced) | v2.0.0, 95 blocks (Pathfinder, Ranger, Controller, IMU, Vision, MBC common), for protocol v2 firmware. This is an import file: sign in to ext.mblock.cc → My extensions → Import data → upload → Download the final .mext. Once listed, just search "MBC" in the mBlock Extension Center |
| MBC_Pro_Sensors_mBlock5_v1.0.0.mext legacy | Legacy | v1.0.0, 15 blocks, for firmware shipped before 2026-10; drop straight into mBlock |

SPIKE / EV3 Pybricks examples (.zip)
The current version is Pybricks 4.1 (the stable code.pybricks.com is v4.1.1; v4.1.0 from the MBC SPIKE Blocks website works too). Every pack includes MBC_sensors.py: one file for every MBC sensor (shared by SPIKE and EV3). New projects only need to import it: from MBC_sensors import MBC_LINE8 (classes: MBC_LINE8, MBC_LINE16, MBC_LASER2, MBC_LASER8, MBC_GAMEPAD, MBC_CAM_SCHOOL, MBC_HUE12).
Important
The old-name libraries in the packs (such as
MBC_line8_obj_Lib.py) are for swapping into existing projects: an old project just replaces the one file it already uses, with no code changes. Every old-name file is the whole shared library, so importing 3 or more in one program goes over the SPIKE program slot limit of about 51 KB; to mix several sensors, import onlyMBC_sensors.py.
