The reference designators on the Bitsy G5 are labeled differently than the previous four
generations of Bitsy family products or mating personality boards. The reference designators for
the Bitsy family products are given in the following sections with the Bitsy G5 reference
designators shown as (Jx).
3.3.1
J1 (J8): LCD Panel Interface Connector
Board Connector: 2x17 shrouded header, 2 mm, Samtec STMM-117-02-G-D
Recommended Board-to-Cable Connector: TCSD series
Recommended Board-to-Board Connector: ESQT series (e.g. ESQT-117-02-F-D-500)
The following table describes the signals on the LCD panel interface connector. Signal names
shown are for TFT active matrix color LCDs at 18 bpp (bit-per-pixel). Signals from the i.MX31
are buffered and RFI filtered before reaching J1 (J8). The LCD panel output buffers operate at a
fixed 3.3 V.
