Banggood

nice one

This is the module powering my DSO Shell oscilloscope at about 9.5V from an 18650 cell. It shows about 10-15mV ripple at around 10kHz(?).

A premier vue bon ne qualité, mais a tester

je recommande

Das Einstellen der gewünschten Ausgangsspannung gestaltet sich zwar etwas schwierig( man muß sehr lange drehen eh überhaupt etwas passiert, dann reicht eine kleinste Bewegung des Schraubendrehers und man ist weit drüberraus), hält dann aber die gewählte Spannung ganz gut(auf 0,5V genau). Paßt gut auf ein 2S Li-Ion-Case.

Thanks for this merchant's sincerity in the transaction The merchandise is arriving as described without defects, working properly, and well packaged I arrived ahead of time Thank you again

Arrived fast, safe and sound. One piece was checked with 5V input and around 20V output at about 20 mA. The item performed as it expected. A huge (14V) ringing of 153 MHz appears after every switching transient. For me it worth it's price.

Works good 5 volts at 2 amp's, 28.15 volts out.You need 2 amp's to get it work well and adjust the trim pot.

Small, light voltage booster, particularly for FPV plane using 2S batteries to get 3S voltage for TX, cameras, etc.

All as described. Will do 2A out at low Vin-Vout difference. Works well for small projects!
