In this thread, you will be able to make an order for a driver with your desired specs, Once I complete the building and testing I will upload pictures here, Also I would like this thread to be kind of a 'feedback centre' With both positive and negative feedback, Also any technical questions about my drivers will be answered here.
Current pricing:
3A buck: 22 Euros/25USD + Shipping(approx 6-10 euros depending on destination)
1A boost: Available soon
Small form factor 1A buck: In development
1A buck-boost: In development
High current boost: To be developed
Datasheets:
3A buck: http://www.mediafire.com/file/la063h09tlzoqp1/3A_buck_datasheet.pdf/file
1A boost: WIP
Extra options applicable for all:
Extra precision and low tempco set resistors +50c per 3 values of your choosing (will expand stock soon)
Extended testing: Full test report +7$ (Will be testing every possible aspect and will characterize your driver with more scope waveforms, Efficiency graphs corresponding to different Vins and more)
My goal with all this: My goal is to make as affordable drivers as possible without cutting any corners besides getting paid 0$ for my time, earning about a dollar or 2 per driver due to the "basic" testing included with each purchase already being over the top. I also try to include as many features as possible and only buy components from brands as TDK(capacitors), Panasonic(Automotive-grade inductors), Texas Instruments, Analog Devices, Linear tech and STM for ICs, Walter elec(High accuracy Low tempco resistors) And US made gold plated PCBs from OSH(tighter tolerances, better base material etc) being about 3x as expensive as the normal JLC other driver makers use(you are able to tell due to the order numbers on their PCBs). Drivers are packaged in ESD bags with the included basic test sheets inside. Also Please excuse any solder spills you may find on your drivers since I hand assemble and test each one individually.

G,
I’m interested in your 5mmx5.3mm boost driver idea you spoke of a while back. Are these going to be in your lineup of available drivers? Thx

I really wouldn't think that people would be interested in them since they are only up to 200mA and reverse pol protection like my other drivers, Tell you what, I'll do a small run of 5-6 of those in the next month or 2. Shipping is what will delay us here. Components get to me in ~1 month and PCBs will get here in a week since I am forced to use fedex int priority due to the cheaper option taking 2.5 months.

I would be interested in one or two of those. they sound interesting.

Ok just ordered PCBs for the 1A boost(didn't show up In time so re-ordered) 17mm 3A buck, and 5mm x 5.3mm boost. Expect datasheets and them in stock in approx 1-month max, Most likely 2.5 - 3 weeks.
