Ring:bit v1.0(EF03423)

Introduction​

Ring:bit is a simple module based on micro:bit. It can lead out 3 IO connectors, power connectors, ground connectors on the micro:bit board. On this module, we have transformed P0/P1/P2 into general connectors for GVS electric bricks. Among them, we have extended P2 to a GVS connector with multiple usages. There is a slide switch on the board. Slide the switch to “S”, then you can connect SR and SL2(digital signal modules) at the same time. Slide to “P2”, you can connect digital module or simulating module but only one of them. This module adopts 3 No. 7 batteries for power supply. It is very simple, easy and practical to use. With this module, you can drive all kinds of GVS modules like servos, line-hunting modules and LED modules.

Connectors​

More Details about Some Connectors​

Function Selection Switch​

Switch for S and P2 connector selection. Shift to “S” means SR in P2 connected to SL. At this time, you can connect two GVS modules to connector G-V-SR and G-V-SL separately. Shift to “P2” means use the connector of P2 only.

G-V-S P2 connector​

Only when function selection switch has shifted to P2，these two connectors can be used. It is compatible with partial products of Octopus Bricks series

G-V-S SR/SL Connector​

Only when function selection switch has shifted to S, we can use the connector. It is compatible with partial products of Octopus Bricks series

Code Example​

Electric circuit for mini elephant car line-hunting:

Fix micro:bit board:

G-V-S P0 Connector​

P0 connector can be used as digital IO connector, analog IO connector or PWM output signal connector.

G-V-S P1 Connector​

P1 connector can be used as digital IO connector, analog IO connecotr or PWM output signal connector.

Dimension​

Software​

Fix micro:bit board and servo.

Code Example：

The three servos rotate clockwise first, anti-clockwise after 1 second, then clockwise again in the next 1 second. Repeat this movement forever.
