AC320101

MEB/MEB II UART-to-USB Adapter Board Information Sheet The MEB/MEB II UART-to-USB Adapter Board (AC320101) uses the MCP2200 Breakout Module (ADM00393) to convert USB-to-UART signals that can be accessed directly by the PICtail connector on either the Multimedia Expansion Board (MEB) DM320005 or the Multimedia Expansion Board II (MEB II) DM320005-2. The four jumpers on the board can be used to route the UART signals to either the MEB or MEB II. For more information, refer to the MCP2200 Data Sheet (DS20002228) and the MPC2000 Breakout Module, which are available for download from the Microchip web site at: MEB/MEB II UART-to-USB Adapter Board Schematics 5V J1 1 VBUSVBUSS VUSB U2 VDD 2 USB N 5V VDD D-D- MCP1700 R1 VDD USB P 3 3 2 3.3V D+D+ VINVIN VOUTVOUT 5V 4.7k C5 4 12 3 IDID C1 J2 0.1uF C2 C3 5 4.7uF 0.1uF 0.1uF HDR M 1x3 VERT X1 12MHz GGNDND 1 3 USB-B-Mini SMD JP1 Jumper VDD U1 1 20 VVDDDD VSSVSS 2 19 C4 VDD USB P J5 OSC1OSC1 D+D+ TX 3 18 J4 USB N OSC2OSC2 DD-- 0.1uF J3 4 17 RSTRST VUSBVUSB VUSB VDD 5 16 GP7 GP7/TxLEDGP7/TxLEDDDGP0GP0 6 15 GP6 GP6/RxLEDGP6/RxLEDDDGP1GP1 GP0 CTS 7 14 GP5 GGP5P5 GP2GP2 GP1 RTS 8 13 GP4 GP4GP4 CCTSTS GP2 9 12 GP3 GP3GP3 RRXX RX CTS RX HDR M 1x6 VERT 10 11 TX TXTX RTSRTS RTS RX MCP2200 PICkit Serial HDR M 1x7 VERT HDR M 1x7 VERT (DNP) (DNP) ADM00393 (MCP2200 Breakout Module) JP1 Shunt 2.54mm 1x2 Handle JP2 Shunt 2.54mm 1x2 Handle +3.3V JP3 Shunt 2.54mm 1x2 Handle J1 JP4 Shunt 2.54mm 1x2 Handle J4 J2 1 MEB2 CTS TxD MEB2 CTS CTS MEB2 RTS 2 GND MEB2 RTS RTS MEB2 TxD 3 J3 4 MEB2 TxD TxD CTS MEB2 RxD RxD MEB1 TxD MEB1 TxD TxD 5 RTS MEB1 RxD MEB1 RxD RxD 6 RxD HDR-2.54 Male 2x4 MEB2 RxD MEB1 CTS MEB1 CTS CTS HDR-2.54 Male 1x6 MEB1 RTS MEB1 RTS RTS HDR-2.54 Male 2x4 GND HDR-2.54 Male 2x14 TM PICtail Connector 7 5 3 1 8 6 4 2 1 GNDGNNNDDD 6 5 4 3 2 1 27 25 23 21 19 17 15 13 11 9 7 5 3 1 28 26 24 22 20 18 16 14 12 10 8 6 4 2 7 6 5 4 3 2 1 2 7 5 3 1 8 6 4 2 7 6 5 4 3 2 1
