BaseCam SimpleBGC 32-bit Tiny
This controller is a smaller version of SimpleBGC 32-bit 3-axis stabilization. It is designed for building gimbals for small cameras.
Built-inIMU sensor, can be used as a second frame sensor or as the main sensor.
- Has the same set of interfaces as the full-size SimpleBGC 32-bit.
- Possibility to connect optional Bluetooth module.
Revision C (Active)
- Fully compatible with the "Tiny Rev. B" in shape, terminals, and mounting holes.
- Dimensions are 25×40 mm, height is 7mm (pin headers are not installed)
- Output power capabilities up to 6 times more than in Tiny Rev. A and B, which allows using this board with a wider range of payloads, handling motors from micro-size to 110-size.
- High-voltage motor drivers are connected directly to the power supply, giving the following advantages compared to Rev. A, B*:
- overall output current is limited only by the power supply capabilities;
- can handle high-voltage motors and big motors up to 110 sizes;
- better reliability
- Motor drivers have better efficiency (less heat emission at the same output power)
- MCU with 256k FLASH (2x more than in previous revisions) can support advanced functionality which presents in the "Extended" series of SBGC32 controllers**
* For maximum current capabilities good thermal dissipation should be provided;
** Supported functions depends on the license type. See Version comparison chart
Drivers in rev.C are more efficient but produce more EM interference compared to Rev. A, B; special actions are required to prevent interference on digital signal lines (I2C or PWM) and nearby electronics:
- installing filters on the power supply cable (several turns on a ferrite ring); limiting its length to 70 cm;
- installing filters on motor outputs and/or shielding the cable:
- LRC-filter (see schematics)
- ferrite ring on the cable
- installing filters on the digital signal lines (several turns on a ferrite ring); using twisted pairs for I2C (SDA+VCC, SCL+GND) and/or shielding them.
Revision D (Active)
Retains all parameters of Rev. C with some improvements:
- Motor drivers emit less EMI noise and a bit more powerful
- Optional CAN bus interface (requires special firmware and external CAN transceiver)
Revision A (Discontinued) & Revision B
Not recommended for new design
For more information on Rev. A and B check their product page
The main difference from revision C:
- low-voltage motor drivers (max. 11V) powered from integrated DC/DC converter, where the overall current is limited by the DC/DC converter max. capabilities (about 1A); can handle only low-voltage motors;
- MCU with 128k FLASH supports only basic functionality of "Regular" and "Tiny" series;
Revisions A and B may be manufactured in batches by request; we keep a limited number of Rev.B in stock.
|Revision B||Revision C||Revision D|
|Size of the board||40×25×7 mm|
|Weight:||5.84 g||5.45 g|
|Power supply voltage||3.7—25 V (1s - 6s LiPo)||5—26 V (2s - 6s LiPo)|
|Maximum motor current||1A per motor
1.5A for all
~1.5A continious per motor*
~2A continious per motor*
|5V converter output||up to 1A|
* Board uses a dedicated PCB layer (almost 100% of its area) for a heat dissipation. The overall current capabilities of 5V regulator and motor outputs are limited by the thermal dissipation; it can be improved installing external heatsink.
USB Drivers for PC Connection
If controller being connected to the USB port, is not recognized as COM-port, most probably you need to install or update drivers for CP210x chip. You can download driver for your OS from the manufacturer of CP210x.
AN IMPORTANT NOTE: The latest version (6.7.4) of driver for Windows may cause problems with delay in data transmission, visible as a big lag of the GUI. In this case, install version 6.7.2 of the driver, which had no such problems.
