We have added a new higher current range potentiostat to the electrochemistry product line! The new Rodeostat HC is very similar to the Rodeostat Open Potentiostat, except the measurable current ranges are ± 10, 100, 1000 and 10,000 μA.

Community request for a higher current measurement option
The Rodeostat can be used to measure up to 1000 μA, which we have been learning can be limiting for some applications. We have had a few requests from users that need to measure in the mA range. For example, the user below was struggling with the 1 mA limit on the Rodeostat for high-range metal measurements:
Another Rodeostat user needed a higher range for measurements of solar cells:
To increase the Rodeostat capability beyond ± 1mA required a small hardware change. We changed the feedback resistors used in the feedback loop of the transimpedance amplifier so that the current ranges are now ± 10, 100, 1000 and 10,000 μA.

Rodeostat HC
The Rodeostat HC is a higher current range version of the Rodeostat open source potentiostat. The Rodeostat HC includes a 3D-printed enclosure, pre-programmed ItsyBitsy M4 Express, micro-USB cable, set of 3 alligator clip cables and a 50K dummy cell.
