MC-101 mbed Compatible Baseboard

Jumper Configurations:

  • JP2 -- Ethernet Green LED enable (#7 on diagram below): Default=Installed. Installing the jumper connects p30 to the green LED on the Ethernet connector. Removing this jumper allows unfettered use of the p30 I/O pin from the mbed header.
  • JP3 -- Ethernet Yellow LED / SD Card Detect selector (#7 on diagram below): Default=2:3. Jumper 1:2 (left position) to use p29 for detecting the presense of an uSD card. Jumper 2:3 (right position) to use p29 for the yellow LED on the Ethernet connector. Removing this jumper allows unfettered use of the p29 I/O pin from the mbed header.
  • JP4 -- Serial level shifter disable (#11 on diagram below): Default=Removed. Installing the jumper will put the RS232 level shifter into shutdown, saving some power (may be useful if you are running on battery). The DB9 serial port will not function with this jumper installed.
  • JP5-JP8 -- RS232 DB9 / SPI (DIO) selectors (#15 on diagram below): Default=2:3. These jumpers route p11-p14 to either the screw terminals or the RS232 port (for extended signaling). Jumper 1:2 (upper position) for RS232 CTS/RTS/DTR/DSR functionality, or jumper 2:3 (lower position) for SPI/DIO functionality on the screw terminal block. These jumpers can be mixed between the two positions depending on your needs.
  • JP9,JP10 -- RS232 DB9 / PWM (DIO) selectors (#12 on diagram below): Default=2:3. These jumpers route p21-p22 to either the PWM headers/screw terminals or the RS232 port (for extended signaling). Jumper 1:2 (upper position) for RS232 DCD/RI functionality, or jumper 2:3 (lower position) for PWM/DIO functionality on the headers/screw terminal block. These jumpers can be mixed between the two positions depending on your needs.
  • JP11 -- 3.3V or 5V selector for Pin 1 ouptut voltage on terminal block JP14 (#19 on the diagram below). Jumper 1:2 (left position) for 3.3V, 2:3 (right position) for 5V.
  • JP12 -- 3.3V or 5V selector for Pin 1 ouptut voltage on terminal block JP15 (#20 on the diagram below). Jumper 1:2 (left position) for 3.3V, 2:3 (right position) for 5V.
  • Warning! Do not install jumpers on JP17-JP22 (#13 on the diagram below). They are Futaba compatible servo headers. When using servos be sure to connect an external power supply (#1 on the diagram below), do not rely on the mebed USB to power them.
