It is custom. I bricked the original throttle somehow and made a simple throttle here: A Simpler Throttle - #16 by jerix
Because it had no screen I offloaded altitude and telemetry information to a custom app I made. But it only displays the information it gets via ble from the throttle. The throttle uses the same code to deserialize the telemetry data as the SP-140 throttle for the ESC 2.0.
All other values seem completely normal only Amp and thus the wattage values spike sometimes
