Robert,
I am working with the REV 4 board and have a few questions ( one listed in Home / DRIVER BOARDS / PCB DRV8825_HW203_IR_BT_WIFI_REV4). I think this is the latest of the full version.
1) Is there a listing showing what part plugs in where? I can tell most based on the board side schematic but I can't find what goes to JP5, JP6, JP12, JP14. Looks like the toggle swtiches go on JP8 and JP9?
2) The parts list call out two switches but looks like the board schematic has 3? JP7, JP8 and JP9.
3) There are two 470 resistors shown on the schematic near JP5 and JP6 but not listed on parts sheet. Are these no longer needed?
4) Are the 1k and 2.2k resistors founded under the Arduino just for the wifi circuit and if not using the wifi can these be left off the installation.
I'm just a novice with this stuff so it may be listed and I'm just missing it. Thanks.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
JP5 = jumper for Blue LED - short if not using a pre-wired led, open if using led+470 ohm resistor
JP6 = jumper for GREEN LED - short if not using a pre-wired led, open if using led+470 ohm resistor
JP12 = Short for normal program operation, remove if reprogramming firmware - or use toggle switch
JP14 = Power LED jumper - short if not using a pre-wired led, open if using led+470 ohm resistor
JP8/JP9 = push button switches for IN/OUT
JP7 = On off toggle switch for power
3) if using prewired 5V leds which has a resistor already wired in series with LED, then no need for 470 ohm resistors
4) yes can be left off but solder them anyway in case you want to try wifi/bluetooth later
