The STorM32 v1.31 boards, which are distinguished by their on-board switching regulator, unfortunately provide a very weak 3.3 V power supply, which makes it problematic to use NT modules. Therefore, usually extra BECs need to be used with these boards.

Rcgroups user ckambiselis has suggested a, relatively simple, mod to fix that issue. For the original post see [here].

It consists of three steps:

(1) Removal (desoldering) of the 3.3 V LDO regulator from board.

(2) Soldering of a stronger 3.3 V LDO regulator to the bottom of the board.

(3) Soldering of two wires to establish the connections.
