Just noticed that the Arch Pro silkscreen for the Grove connectors is labelled 5V on the underside of the PCB, and 3V3 on top. With R50 populated by default, they are almost always going to be 3V3.

Also noticed that on the pinout diagram above, the third pin from the top on the right hand side is mis-labelled (should be P2_13).

It would be very helpful it the pinout diagram had the corresponding standard mbed DIP pinouts for cross reference. As far as I can tell from comparing schematics, the following are the mappings of the blue pins... hopefully helpful to someone. Left hand side: P2_12=N/A, P0_23=DIP15, P0_24=DIP16, P0_25=DIP17, P0_26=DIP18, P1_30=DIP19, P1_31=DIP20 Grove: P2_0=DIP26, P2_1=DIP25, P0_10=DIP28, P0_11=DIP27 Right hand side: P0_28=N/A, P0_27=N/A, P2_13=N/A, P0_7=DIP7, P0_8=DIP6, P0_9=DIP5, P0_6=DIP8, P0_1=DIP10, P0_0=DIP9, P2_5=DIP21, P2_4=DIP22, P2_3=DIP23, P2_2=DIP24, P0_5=DIP29, P0_4=DIP30, P4_28=N/A, P4_29=N/A SPI: P0_17=DIP12, P0_15=DIP13, P0_18=DIP11, P0_16=DIP14

Grove VCC defaults to 3V3, but can be changed to 5V by moving R50 to R51 SPI VCC pin can be set by populating R52 (3V3) or R53 (5V) wirh 0R - neither populated by default

Hi Kean,

Thanks a lot. P2_13 is fixed now. We will draw a pinout diagram with mbed LPC1768's pin name and add the document of Grove VCC and SPI VCC to wiki.

I'm a novice. This board shows only 25kB of Flash,so I can't load any program. However, Nucleo 401RE shows 512kB. Does someone have information about that?
