Flashlight Firmware Repository

There are a lot of different circuits which can be called “a 7135 driver”.

Is there a driver schematic repository? I’m sure all the old hands know what pins go to where and the values of the passives from memory. I don’t.

I’m working out the Convoy 3/5 mode driver. It looks similar to a Nanjg 105C. Schematic for the Nangj is

LED Driver Schematic

Here is a schematic for the NANJG 105C. Let me know of any errors or omissions and I’ll update the pic or add corrections to this comment. [image] Notes: When looking at the battery side of the driver, the stars are number from right to left. +Vin is the spring in the middle, -Vin is the ground ring on the edge of the driver. R1 and R2 form a divider for battery level measurement and power cut detection. D1 provides reverse batrery protection for the MCU, reduces the incoming voltage (driver…

Vcc cap and PB2 voltage divider appear to be the same but with different values. PB1 (pin 6) is connected to the 7135s.

Pins 1,2 and 3 are n/c ?
