2xLM2596 DC-DC Adjustable Buck Converter Step Down Module 1.23V-30V

Mar 21, 2020

Inexpensive and easy to use, but gets too hot if you need 1 amp or more

Inexpensive and easy to use, but don't try to get anywhere close to the rated 3 amps. I set mine for 2.8v output driving a 1-ohm load (2.8 amps), and the entire PC board got too hot to touch within a couple minutes. I was afraid to leave it running as I'm sure the heat would have continued to increase until something fried. Also, at that setting it was only 64% efficient (over 12 watts in for less than 8 watts out). That's no where near the advertised 92%, which explains the heat problem. This board would probably be fine for less than 1 amp, but I would not recommend it for anything over that.

MG995 360° High Torque Metal Gear RC Servo Car Motor Set For Boat Helicopter

Mar 09, 2019

Does rotate 360° with CW and CCW motion, but difficult to control and limited torque at low speeds.

The good news - it is a 360° servo with decent torque and speed. The bad news - torque decreases significantly as rotational speed is decreased and is pretty much useless at low speeds. At 2-3 rpm the torque is so low you can easily stall it with a finger, and that's with the supplied horn that is only about 1cm long. Higher speeds it has good torque (very hard to stall) but if you need to move something with any weight or resistance at a slow speed I don't see how this would work. Also it has only about 40 steps from stopped to full speed and a huge dead spot (110us) between CW and CCW. Info I determined from experimenting with Arduino Uno: Full speed CW 1396us Slowest CW 1435us Stopped - anywhere between 1435us - 1547us Slowest CCW 1548us Full speed CCW 1587us

W1209 12V -50-110°C Digital Thermostat Temperature Control Switch Sensor Module

Apr 22, 2021

Good module but I suggest using an external relay for high currents

After a couple weeks of operating an 8-amp resistive load it stopped working. Either the relay, PC board trace, or terminal strip overheated and fried, it was too burned to tell where the problem started. Price is good and the module works well, just watch out for high-power loads.
