The motor driver control circuit includes a first H-bridge and a second H-bridge. The first connector is a connector to which an output from the first H-bridge and an output from the second H-bridge are input. The first wire and the second wire input the output from the first H-bridge to the first connector. The third wire and the fourth wire input the output from the second H-bridge to the first connector. The fifth wire is connected to the first wire and outputs the first H-bridge output to another connector. The sixth wire is connected to the second wire and outputs the first H-bridge output to the other connector. ## Claims ### Claim 1 A board comprising: a motor driver control circuit including a first H-bridge and a second H-bridge; a first connector to which an output from the first H-bridge and an output from the second H-bridge are to be input; a first wire and a second wire configured to input the output from the first H-bridge to the first connector; a third wire and a fourth wire configured to input the output from the second H-bridge to the first connector; and a fifth wire connected to the first wire and configured to output the first H-bridge output to another connector, and a sixth wire connected to the second wire and configured to output the first H-bridge output to the other connector. ### Claim 2 (depends on 1) The board according to claim 1, further comprising the other connector. ### Claim 3 (depends on 1) The board according to claim 1, further comprising: a seventh wire connected to the third wire and configured to output the second H-bridge output to the other connector; and an eighth wire connected to the fourth wire and configured to output the second H-bridge output to the other connector. ### Claim 4 (depends on 1) The board according to claim 1, further comprising: a processor; and a ninth wire configured to connect the other connector and the processor. ### Claim 5 (depends on 4) The board according to claim 4, further comprising a tenth wire configured to connect the other connector and the processor. ### Claim 6 (depends on 1) The board according to claim 1, further comprising: another motor driver control circuit different from the motor driver control circuit and including a third H-bridge and a fourth H-bridge; and a second connector to which an output from the third H-bridge and an output from the fourth H-bridge are to be input. ### Claim 7 (depends on 1) The board according to claim 1, wherein the motor driver control circuit is a motor driver control circuit configured to drive a motor that outputs a lock signal. ### Claim 8 (depends on 1) The board according to claim 1, wherein the motor driver control circuit is a motor driver control circuit configured to drive a stepper motor. ### Claim 9 (depends on 1) The board according to claim 1, further comprising a non-mounting area where a motor driver control circuit different from the motor driver control circuit can be mounted, wherein at least four wires extending from the non-mounting area are formed in the non-mounting area. ### Claim 10 An electronic device comprising: a board having: a motor driver control circuit including a first H-bridge and a second H-bridge; a first connector to which an output from the first H-bridge and an output from the second H-bridge are to be input, a first wire and a second wire configured to input the output from the first H-bridge to the first connector, a third wire and a fourth wire configured to input the output from the second H-bridge to the first connector, and a fifth wire connected to the first wire and configured to output the first H-bridge output to another connector, and a sixth wire connected to the second wire and configured to output the first H-bridge output to the other connector; a stepper motor; and a wire rod configured to connect the first connector and the stepper motor. ### Claim 11 (depends on 10) The electronic device according to claim 10, wherein the stepper motor is a motor configured to drive a developing machine of a printer. ### Claim 12 An electronic device comprising: a board having: a motor driver control circuit including a first H-bridge and a second H-bridge; a first connector to which an output from the first H-bridge and an output from the second H-bridge are to be input, a first wire and a second wire configured to input the output from the first H-bridge to the first connector, a third wire and a fourth wire configured to input the output from the second H-bridge to the first connector, and a fifth wire connected to the first wire and configured to output the first H-bridge output to another connector, and a sixth wire connected to the second wire and configured to output the first H-bridge output to the other connector; a first direct current (DC) motor; a second DC motor; three wire rods configured to connect the first DC motor and the other connector; and three wire rods configured to connect the second DC motor and the other connector. ### Claim 13 (depends on 12) The electronic device according to claim 12, wherein the first DC motor is a motor configured to drive a fan.
