These are high quality sealed Single Pole - Double Through (SPDT) relays. This relay's coil is rated for 5V. The nominal operating current is 72mA so it will need additional circuity to close the relay with a microcontroller like an Arduino or SBC such as a Raspberry Pi or BeagleBone Black.
This is a High current driver that will take TTL signals from your Arduino, etc to drive the relays. It includes status LEDs for each input. 5V, 12V, and 24V relay options are available. This item replaces TE-010-405 and TE-010-412
RELAY GENERAL PURPOSE DPDT 8A 5V
Used for testing, TF02 Single Point Ranging LiDAR, connectors have been changed for testing.
This is a direct drive 4WD robot kit that uses Nexus mecanum wheels. The mecanum wheels allow it to vector in any direction.
