NOTE - this layout had serious issues in regard to the gyro connections which I am currently rectifying in the v2 layout to follow.An STM32F405 brushless quadcopter flight control board. All UART’s and SPI3 broken out along with SWD programming connections. Suitable for configuration with SilF4ware software by Markus Gritsch on RCGroups. See here https://www.rcgroups.com/forums/showthread.php?3294959-SilF4ware-an-STM32F4-port-of-SilverWare Currently awaiting prototype PCB’s for testing so build at your own risk.

This is the third version of the SilverLight 5vFPV. This has the XTAL moved right away from the inductor for the 5v power supply which was causing interference in the RX circuit in the original SilverLight 5vFPV design. I also addressed a number of other relatively minor design flaws / improvements like -

numbered the ESC connector end pins 1 & 6

moved the 5v socket away from the programming socket as they were too close

fixed the wrongly labeled ADC / VIN pads

moved the XTAL caps closer to the XTAL

fixed the XN297 footprint which was too wide

modified the DRC so that the vias are now tented (covered with solder mask)

Moved the ESC connector over and added two VIN pads. I do not like putting up to 4S in through the tiny VCC and GND pins of the ESC connector especially if there is an FPV camera/ VTX also being used as well as power for the FC"

NOTE - this version had radio problems so these have been resolved in SilverLight Eagle 5v_v2 A slight reworking of the SilverLight FC by Ian444 on RCGroups which is based on the brushed Eachine toy quads. The BOM is available here https://www.rcgroups.com/forums/showpost.php?p=40125347&postcount=628 with other info spread throughout that thread. Just search all posts there by Pedro147. This version of the FC has regulated 5v for FPV and a 6 pin JST socket for direct connection to 4 in 1 ESC’s.
