NANDO Eagle PCB (48pin ZIF)

[kooroshi60]

Here is an another variant of PCB for this great project. (Eagle 9 Format + PDF) -Since the track clearance is .15mm, this PCB has to be made with Photo Resist film technic. Toner transfer method is not precise enough. -This is a double layer PCB so don't forget to solder VIAs. -All the components except the USB connector are SMD. -You can find the value of the components in the Eagle files. -You can either use a 48pin ZIF IC Socket or 4 rows of pin headers in order to support 7.2mm and 15.24mm ZIFs. -There are 18 pins of the socket which need a VIA wire. Other pins of ZIF socket and the USB connector are routed from Bottom layer. NANDO Bottom.pdf NANDO TOP.pdf Nando_ZIF48_USBb.zip

I was wondering if it is possible to use the STM32f103VET6 instead of VCT6? VET6 is a bit more expensive; but what if some one has it available?! Based on the datasheet, the only difference is the flash memory size. Actually I had done this before on a STM32 development board and it works.

Thanks for sharing ZIF schematic. VET6 and VDT6 should also work, the redundant memory will not be used.

And here is a picture of the completed Nando programmer. Many thanks to Mr. Bogush

Very nice PCB. Thank you!

I created a programmer like yours based on your PCB file. The trouble now is that I have searched the internet for a suitable hex file for this programmer. Could you please send the hex file of your programmer? My email address is 401707682@qq.com

@ucsoom all hex files are located on Google driver https://drive.google.com/drive/folders/1AGWV5_WANd6tItfXJFq4AlQePkRsusNU

可以用STM32cubeide开发hal库的固件，移植难度很小。
