COK-001 revisions related with daughterboards

Facts
- CECHA and CECHB uses COK-001 motherboard
- CECHA has wifi/BT by using a daughter board named CWI-001 fully populated with components, also card reader using another daughter board named CMC-001
- CECHB does not have wifi... but uses the same daughter board named CWI-001 where some components are missing, also it does not have card reader daughter board
- COK-001 had at least 3 revisions, based in the serials reported: 1-871-868-12 (first revision), 1-871-868-22 (second revision), 1-871-868-32 (third revision)

Fictions
- So it seems there are different COK-001 motherboards... the motherboard PCB itself is the same but for CECHB some components are missing (the ones related with the wifi/BT.... and maybe some more related with card reader)
- Is not clear is is posible to know this differences based in the serials (the 3 revisions COK-001 had)

Note the components missing next to the connector (the big squared one looks like a fuse/thermistor and should be specific for wifi module)

BT module is the one at left... and wifi the one at right
