In the early days of Trilogy modules (White Whale, Meadowphysics, and Earthsea), connected grids pulled power from the +5v rail on Eurorack power supplies – often, up to 600mA. The power supplies in the market at that time often didn’t provide enough power, so we used to offer external 5v solutions. These are no longer sold as robust +5v rails are more common, though we always recommend keeping an eye on your consumption by calculating your power draw against your power supply with modulargrid.
If you wish to DIY an external power solution for grid, please check out Offworld.
With Ansible, the +5v rail is no longer used – instead, grid pulls from the common +12V rail (200mA maximum).
If your Teletype does not have a black circuit board (which we started manufacturing in December 2018), it is not recommended to plug grid directly into Teletype’s USB port. The older models with green boards are not designed to supply enough power through USB, which won’t harm your equipment at all but it will reset the voltage regulator and cause instability. Our recommendation is to power the grid externally when plugging into Teletype, regardless of board color, as this also reduces the likelihood of noise. two > one was designed specifically for this purpose.
If you are experiencing noise in your system as you use grid (there are no hard-and-fast rules for which case power supplies will cause or avoid ground loops), we recommend powering grid externally and connecting only the data line to your modular system. This can be achieved using a ground loop adapter similar to this one from Expressive E. This will ensure isolation between the grid and your system’s audio path. Please note that by decoupling the power from your modular system, you’ll need to unplug the grid after playing in order to turn the grid’s LEDs off.
