BGC v3.15 2-Axis Brushless Gimbal Controller, MOS Drive, SimpleBGC

The BGC v3.15 is the original 8-bit BaseCam SimpleBGC gimbal controller, the board design that established much of the DIY camera gimbal hobby before the newer 32-bit SimpleBGC boards arrived. While that 32-bit version has since superseded it as BaseCam's current flagship, this 8-bit board remains sold and actively supported, and the newer SimpleBGC configuration software still works with it, so builders are not locked out of ongoing software improvements just because they chose the older, less expensive board.

It drives gimbal motors through a MOS tube design rated for a larger current than simpler driver designs, with a peak current rating of 10A, and supports a wide range of 2 to 8-series gimbal motors. Used on its own, it runs a 2-axis gimbal (pitch and roll, or pitch and pan depending on setup); adding the matching extension board upgrades it to full 3-axis control. Configuration happens entirely through the SimpleBGC GUI, available for PC, Mac, Linux and Android, connected over the board's onboard USB port, with the one firmware caveat that the GUI version used must be equal to or newer than the firmware actually flashed onto the board.

The supplier's own listing carries a clear warning worth repeating: don't flash or update the board's default firmware casually, since doing so can cause PC connectivity problems, and misuse of the controller more broadly can damage the board. A recommended setup uses a 12V (3S battery) power supply, a camera mounted firmly and securely, and a properly tightened drive belt where the gimbal design uses one.

The package includes the 2-axis controller board itself, a gyro sensor on a 30cm cable, and a connecting cable. Builders already running 2204, 2208 or 2805-class gimbal motors and needing a proven, well-documented controller board to drive them, without paying for the newer 32-bit board's extra features, will find the BGC v3.15 a capable, cost-effective choice.
