5V & GND Stabilised 5 V/DC/1000 mA are available at these pins. This connector is available for proper extensions and experiments ("5V" =
positive pole, "GND" = negative pole).
3.3V PWR-LED The red LED indicates that the 3.3 V voltage/power supply is working. It lights up when a power supply is connected to the BAT
connector.
5V PWR-LED The red LED indicates that the 5 V voltage/power supply is working. It lights up when a power supply is connected to the BAT
connector.
J7 The jumper "J7" deactivates the evaluation of the PS2-compatible gamepad in the locomotion controller firmware (the robot can
then no longer be controlled via the gamepad). The gamepad control commands can then only be read out via the user board!
ISP-M ISP connector ("in-system programming") of the Locomotion controller. Via this connector the locomotion controller can be pro-
grammed via an ISP programming device. It is also possible to use this connector to integrate your own components with SPI
interface.
PS2-1 - PS2-3 A PS2-compatible gamepad, available as an accessory, can be connected to these pins. With this controller the robot can be con-
trolled manually, similar to a remote controlled car.
J2 & J3 The two sockets are connected to the I2C-BUS connector of the Locomotion controller and can be used for proper extensions. The
connectors are compatible with the "SEEED-GROVE" components.
J4 & J5 The two sockets are connected to the I2C-BUS connector of the user board and can be used for proper extensions. The connectors
are compatible with the "SEEED-GROVE" components.
RESET-M The button triggers a hardware reset of the Locomotion controller when pressed.
S0 - S17 The "leg servos" of the Hexapod are connected to these connections. The pin headers are always arranged in blocks, which are
assigned to the respective leg. The connections for "Coxa - Hip", "Femur - Thigh" and "Tibia - Shin" are counted from the respective
label (S...). The pins are compatible with the most common servos. Make sure the polarity is correct. The polarity is marked on the
board with "SIG" for the signal line, "BAT+" for the positive pole and "GND" for the negative pole.
SA0 - SA5 The analogue inputs SA0 to SA5 can be used for proper extensions in the locomotion firmware. In the "Motion Firmware" these can
also be queried by the user board via a function.
SJ1 The PCB jumper "SJ1" connects the audio amplifier with the locomotion controller. In most practical cases, this connection remains
in place. If necessary, you can carefully cut the jumper with a small wallpaper knife. With a soldering iron and some solder you can
re-establish the connection.
Loudspeaker The loudspeaker is used to output the signal tones and is connected to the audio amplifier. The signal tones can be generated by
the locomotion controller and also by the user board.
Vol. The trimmer "Vol." is used to adjust the volume of the signal tones of the locomotion controller and the user board. If you turn the
trimmer in the direction of the buttons, the volume is increased; in the opposite direction it becomes quieter. In practice, a small
watchmaker's screwdriver has been used to adjust the small trimmer. Be careful not to damage the trimmer when adjusting it! The
basic setting is the middle position of the trimmer.
T1 & T2 The buttons "T1" and "T2" can be used with the user board. Please take a look at the software examples.
SJ6 & SJ7 The PCB jumpers "SJ6" and "SJ7" connect the outputs of the buttons "T1" and "T2" with a 22 kOhm pull-up resistor, so that no
pull-up resistors have to be activated in the user board program. In most practical cases, this connection remains in place. If neces-
sary, you can carefully cut the jumpers with a small wallpaper knife. With a soldering iron and some solder you can re-establish
the connection.
RESET-U The "RESET-U" button resets the user board.
SJ2 The PCB jumper "SJ2" connects the button "T2" with the NodeMCU user board. The used pin of the NodeMCU is the analogue
input and can be disconnected from the push-button "T2" by this jumper if used otherwise. Normally this connection remains in
place. If necessary, you can cut the jumper carefully with a small wallpaper knife. With a soldering iron and some solder you can
re-establish the connection.
SU1 - SU3 The connectors SU1, SU2 and SU3 are connected to the user board slots and can be used for proper applications. They have the
same polarity as the servo connectors of the leg servos. Please take a look at the software examples.
µSD The card slot for a MicroSD card is connected to the Arduino-UNO compatible user board slot and can be used for own applications.
Please take a look at the software examples.
ISP-U ISP port ("In-System Programming") of the Arduino UNO compatible user board slot. This port is used to programme the user board
using an ISP programmer. It is also possible to use this connector to integrate your own components with SPI interface.
The Locomotion-Controller is located under the loudspeaker.
