The Tinywhoop are slowly moving up a gear: they are getting 4S batteries. Of course, electronics must follow the movement, including ESC. There were already the F411 Mini 4S from GEPRC, the F4 Whoop FC 2-4S from SucceX and the F4 2-4S AIO from BetaFPV, compatible with 4S.
Now here is the AuroraRC Supra-F4-12A. It is a 2.85 x 2.85 cm component for 5.6 grams based on an F4 processor. It is flashed with Betaflight and includes an active OSD. It is coupled with a 4 in 1 ESC of 12A for brushless motors, compatible with BLheli_S and Dshot600. The Supra-F4 is equipped with a current sensor and can be used to weld a buzzer. All this can be powered by 4S batteries and an XT30 connector. The price? It will be offered at $39.59 at Banggood Store.
