Gerber file latest version

[manibenwa]

Hai ,

We are developing Nodemcu board and this github has 4 gerber files related to the Nodemcu board which one should i select or which is the latest version gerber file???

It is better to use the PCB source file, not gerber file. I think the latest gerber file is in master branch of this repo, but the most latest gerber file you'd better generate from PCB source file.

Thanks for replay, Where are the PCB source files ?? I haven't found the PCB source files in https://github.com/nodemcu/nodemcu-devkit-v1.0 link!! Please help me....

https://github.com/nodemcu/nodemcu-devkit-v1.0/blob/master/NODEMCU_DEVKIT_V1.0.PcbDoc

This file is the PCB source file, please use Altium designer to open it. All this project is open source and in this repo.

Hai, I found the BOM of this board in this link https://github.com/nodemcu/nodemcu-devkit-v1.0/blob/master/NODEMCU_DEVKIT_V1.0.PDF. I need voltage rating of capacitor and wattage rating of resistors.could u tell me is there any possible way to get the ratings of this capacitors and resistors????

The parameters we actually use is

Designator	Parameter
C1,C4,C6	100nF (104) ±10% 16V
C2	100uF(107) ±10% 6.3V Case B 3528
C3,C5,C8	10uF(106) ±20% 10V
C7	10uF(106) ±10% 25V
D1	SOD-123 40V,1A,VF=0.45V@1A
LED1	1.6x0.8x0.6 Iv= 35~65mcd @IF=5mA ESD:1000V
R1,R2,R3,R4,R5,R7,R8	12KΩ (1202) ±1% 0.0625W [50V TYP] [100V MAX] T.C.R ±100
R6,R9,R11,R12	470Ω (4700) ±1% 0.0625W [50V TYP] [100V MAX] T.C.R ±100
R10(Do not install)	0Ω (0R00) ±1% 0.0625W [50V TYP] [100V MAX] T.C.R ±100
R13	220kΩ (2203) ±1% 0.0625W [50V TYP] [100V MAX] T.C.R ±100
R14	100kΩ (1003) ±1% 0.0625W [50V TYP] [100V MAX] T.C.R ±100
