Is there any programmable driver except for NANJG/7135 ? [With ATtiny or etc.]

[wight]

I started work on the LD-29.

here is the LD-29 MCU pinout (eg how to put your ATtiny13A in there...)

Here we go. The LD-29 has been reviewed by HKJ in two forms, see here: Review/test of LD-29 2.8A 1/2 Cell Circuit board 1-2* Lithium 2-Group 3/5-Mode 2.8A LED Flashlight Driver (LD-29) Mine is from FastTech but I'll note that it uses the taller inductor pictured on the IOS version. It was definitely stacked with wires like the FT model HKJ reviewed (rather than solid pins like the IOS model he reviewed). This board uses the Microchip PIC12F683 (datasheet link) MCU.
