Lite 2S Brushless Flight Controller (Silverware Firmware)
Regular price $29.99 USD Sale price $19.99 USD Save $10.00 USDAfter continuous optimization and research, the high-anticipated Silverware 2S FC has been released now! We provide 2 built in receiver for choice, Frsky D8 (SBUS protocol) and SPI Bayang.
For fans of Silverware firmware, now you could try it with brushless drone like Beta85 Pro 2. The stock firmware is based on brushed NFE_Silverware, which is used on popular ZER0 board.
After 2 months of beta test and upgrade, now it is available for all the pilots. Thanks to all the pilot s who took part in our beta test and gave us feedback and advice.
UPGRADED POINTS
There are tons of upgrade in the final release Lite 2S FC board, both in software and hardware.
Software:
- Add Butterworth Filter on the accelerometer data, solve the issue of drift in level mode.
- Add Smart Audio function for the VTX.
- Solve the issue of vibration and overheat on 110x motors.
- Solve the issue of statics and flash on the OSD information.
Hardware:
- Since to use orange color on the FC with Silverware firmware.
- Built-in physical current sensor.

BUTTERWORTH FILTER
Original Silverware firmware has the bug that accelerometer based drift entering the fusion which manifests as a slower and slower yaw response. This is noticeable in level mode for almost all the Silverware based FC boards.
Now we have fixed it. Filter the accelerometer data first with low pass Butterworth filter and let it participating in flight.
Below is the gravity vector value GEstG[x] drift graph when no correct accelerometer data participates.
OSD MENU
Lite 2S Brushless FC is with build-in OSD which is convenient for changing settings. It supports PID tuning, motor spinning direction changing and channel mapping of AETR in default. The power and frequency of VTX can be switched directly. The operation of OSD Menu on Lite 2S Brushless FC is the same as Betaflight.

FIRMWARE DOWNLOAD
Easily program the Lite 2S Flight Controller with a ST-LINK programmer. Simple plug-n-play operation allows you to update the firmware on your flight controller. The programming port is also compatible with the NewBeeDrone BeeLink USB Flasher.
RECEIVER / VTX CONNECTION & STATUS LED
Here is the connection diagram with external receiver (SBUS protocol):

For other connection diagram with DSMX receiver or M01 VTX, please check the User Manual.
Built-in Current Meter
With build-in current meter, there is no need to use the virtual current meter and you could get a more accurate current value.
Then when flying, you could find the real current value from the OSD information. Of course, the current sensor is configured well in the factory and you do not need to change it as usual.
The built-in current meter is ONLY available on the Frsky version now.
