Connect more than 2 digital Grove Accessories

Hi,

Is there a way/bypass to connect more than 2 digital Grove Accessories?

Thanks

Hi there,
can you expound on this , What is it you are trying to accomplish ?
Are they digital IO’s or i2c or SPI, Grove supports all three.
which Devices and what MCU?

Hi,

For example, 4 Digital LED sticks and Wio terminal. I wish to avoid soldering.

Thx.

Hi there,
I would say YES, but which LED sticks? How do you plan on connection to Wio Terminal
(terminal has two Grove connectors) you could use a port expander or a Piece of the Expansion board that breaks off , leaving 4 connectors.(for no solder solution)

check the WiKi for grove expansion board. :v:

Grove - RGB LED Stick (10 - WS2813 Mini) is the model and which port expander do you recommend?
How can I access each Digital address separately (D0-D3)

Hi there,
Check out the connectors, they (grove) bring out D0-D9
there is only one , the other is a dev board.

Other than the power, how that is connected? Should work fine with those.
There’s a Youtube video or RNerds demo, of that exact connection, and hardware to a Xiao.
:v:
You can use one of these to get solderless access to ALL the GPIO’s

OK. So the grove is limited.

Where can I find the Solderless Pinout Board you mentiond?

Hi there,
You can use the grove connectors on the Wio terminal, Looking at the schematic , D0,D1,D2 & D3 are available there. That rp compatible breakout with terminals is on Amazon, $9-$10 bucs.

use the magnifier up in the corner , and Look for “Grove Expansion” you’ll see avatars next to the topics. look at what I’ve posted previously, pictures, Videos and Code are included. :v:
also the Wiki has easy to find sub topics for specific components too.

FYI

You can either hub or multiplex fependong on your requirements

Hub

this device just connects all the wires together giving multiple connections to a "Bus

Multiplex means a switch that controls which connections are made at any given time

They are only working for I2C as I understand, not for digital.

Hi there,
Indeed they are, How ever this unit breaks out D0,D1,D2,D3 and more.
Check it out, and you can bust off a piece for just the physical connectors.
