Zipit Z2 Connector Pinouts Sheet v0.5 1/24/2011 jpb ----------------------------------------------------------- This is believed accurate, but based on very limited tests. PLEASE VERIFY yourself, before relying on this information. [Rear Port: Expansion Connector] Physically this is a 0.5mm spacing, shielded 36 pin connector, appears same or similar to Hirose ST60-36P Mating plug for solder: Digikey H11462-ND Hirose ST40X-36S-CV(80) Mating plug for PCB: Digikey H11464CT-ND Hirose ST60X-36S Pinout is shown looking into the connector port at the rear of the Z2 --------------------------------------------------------------------- (backside of Z2 LCD screen) top _________________________________________ | 36-pin connector . | ---------|_________________________________________|------- DC [O] |||||||||||||||||| |||||||||||||||||| bottom 36 19 18 1 (ext. +5VDC) Pin# Connected To Function ----------------------------------- 1 4-Pin MIC Port:pin closest to DC Jack 2 3.5mm Base Audio Common 3 3.5mm Tip Left Audio Channel 4 3.5mm Middle Right Audio Channel 5 3.5mm Switch Headphone detect (short to Audio Common = present) 6 4-Pin MIC Port:3rd pin from DC jack 7 CPU 20D GPIO (42) (BTRXD / ICP_RXD) 8 Ground 9 DC Jack + Ext. charger 4.5V ... 6.8V 10 DC Jack + 11 Ground 12 bq24035 pin 20 Ext USB Power Input (4.35V .. 6 V) 13 CPU 19E USB_C Data- 14 CPU 18D USB_C Data+ 15 Ground 16 +1.8 V 17 +3.3 V 18 +3.3 V ----GAP----------------------------- 19 Ground 20 CPU 13AB GPIO (54) CIF_PCLK pixel clock (max 26 MHz) 21 CPU 12AA GPIO (53) CIF_MCLK master clock out to camera 22 Ground 23 CPU 10W GPIO (81) CIF_DD<0> 24 CPU 19F GPIO (114) CIF_DD<1> 25 CPU 12AB GPIO (51) CIF_DD<2> 26 CPU 12W GPIO (50) CIF_DD<3> 27 CPU 12Y GPIO (52) CIF_DD<4> 28 CPU 17AA GPIO (94) CIF_DD<5> 29 CPU 16Y GPIO (93) CIF_DD<6> 30 CPU 7A GPIO (12) CIF_DD<7> 31 CPU 17C GPIO (45) (CIF_PCLK / SSPSYSCLK3) 32 CPU 20M GPIO (86) (SSPRXD2 / USB_P3_5) 33 CPU B20 i2c SDA (to AER913 Pin 6) 34 CPU 18C i2c SCL (to AER913 Pin 7) clock rate: 26 kHz 35 CPU 10Y GPIO (84) CIF_FV camera line start / H.sync 36 CPU 20A GPIO (44) CIF_LV camera frame start / V.sync ----------------------------------- CIF image sensors were often used in video conferencing and early cell phones. One CIF video standard is 352x288 pixels, see also http://en.wikipedia.org/wiki/Common_Intermediate_Format NOTE: I/O pins are NOT 5V tolerant. I/O current source/sink = 3 mA See also PXA270 Developer's Manual p.1174, Table 532: Quick Capture Interface I/O Signal Descriptions http://www.marvell.com/products/processors/applications/pxa_family/pxa_27x_dev_man.pd 276-page Design Guide pdf: http://www.marvell.com/products/processors/applications/pxa_family/pxa_27x_design_guide.pdf 131-page Data Sheet pdf: http://www.marvell.com/products/processors/applications/pxa_family/pxa_27x_emts.pdf TI bq24035RHL Li-ion battery charge controller datasheet http://focus.ti.com/lit/ds/symlink/bq24035.pdf [AUDIO] The headphone jack is a 3.5mm TRS Z2 audio connector pinout 1/24/2011 jpb Audio jack part number: Singatron 2SJ-3545-T01 http://www.singatron.com.tw/userfiles/images_B1/2SJ-3545-T01.pdf ------------------------------------------------ phone 7 9 jack ____ ( ) | | square mic ( ) |____| jack TRS 6 8 mic (EP # = Expansion Port pin #) jack ------------------------------------------------ 6: GROUND (EP 8) 7: REMOTE IN (EP 6) for 6-button resistor network 8: N/C open = no connection 9: MIC IN (EP 1) has +Vbias for electret mic ------------------------------------------------ Physically similar but not same as Nintendo DS headset jack. NDS plug will fit if plastic is trimmed, but contacts only pins 6 and 8 (?) on square mic port. 9: MIC IN goes to RINPUT2 on audio chip, WM8750 pin 25 7: REMOTE IN goes to 80C51 cpu AER915 pin 1 analog in, which talks to main CPU via I2C wired remote circuit: http://russelldavis.org/ZipitZ2/headphone-mic-zipit.png The Z2 board follows the recommended Mic Input schematic on figure 52 of the WM8750 datasheet http://www.wolfsonmicro.com/documents/uploads/data_sheets/en/WM8750.pdf where R1 is 2.2k to MICBIAS and I believe the rest is as shown. External 9:MIC IN is also on pin 1 of expansion port. This pin has a voltage bias for electret mic.
