Question

2-sides pcb + lvds + axp203

bhgv opened this issue 6 years ago · comments

hi,

i did a fork of your blueberry pi, but added LVDS serialiser (SN65LVDS84) with the regular LVDS pin-header, TSC2003 - touch controller, w25q128 - flash, AXP203 power chip instead of EA3036.

and traced them as 2-sides PCBs.

maybe you interested

@bhgv Did you managed to get it up and running with AXP203?

Did you managed to get it up and running with AXP203?

not yet. i'm playing now with a ea3036 one. only received PCBs and soldered it partly. too tight contacts on the ea3036 (and AXP203). i think using lm1117 will be better for this chip/board.

@KaDw
..and on my board wrong connection of the micro-usb. they are mirrored. use full size USB.

@bhgv this issue is resolved with the new version of the PCB

@bhgv i cannot set the default output voltage
in the AXP203 datasheet：

As for more details, please refer to “Default Configuration Instruction”.

Do you have this, can you post it?

Thx
