These are an incredible value. 96-98% efficiency means NO HEAT and NO WASTED POWER.. the days of the TO-220 1A regulator with heatsink and fan are over. It brings shame to what I used to think was an efficient power supply after matching transformer, rectifier, heat sink, and convection cooling. There are two; a 1.8A and a 3A and they are both terrific regulators - power supplies made simple! ** And just as a side note: they arrived faster than a similar order for FETs from Amazon!

The documentation for these floating around the net is Chinese and standard translators have trouble with technical specifications so what has been done by hobbiests is only scraping the surface of the module's capabilities. I translated the entire technical reference and spent many days evaluating it's capabilities. The voice recognition has a very limited vocabulary and although they did provide custom vocabulary integration for bulk purchases; these are surplus modules no longer in production. Voices include Male, Female, and even Children with programmable tone and rate so they are quite flexable in that respect. The quality of the voice is very poor even with external bandpass filtering making it hard to understand unless you know what to listen for. My most fun project with these is "The Battling Bickersons Box" where I entered a whole bunch of insults into a list and alternated random picks using HIS/HER voices.

Very sharp, perfect display for my Raspberry Pi projects. Includes everything you need to connect it and put it to use within minutes of getting it out of the box. Touch sensitivity is very good and precision is quite workable.

I'm now using these exclusively for LED lighting. I've had a couple duds (rare) but have never had one fail once in service. Note: weatherproofing with liquid tape works excellent for outdoor lighting projects.

This is an updated version of the Quick 861DW with a touch-screen digital panel. Popped it out of the box and put it to use immediately. Nice temperature and air-flow control. Settings work same as 861DW with buttons replaced by touch controls. Sturdy build, looks like I can expect a few years service out of this.

All the parts are here, instructions included (gotta love translate.google.com), and it looks like a great little project. I have an arcade machine I built I thought I would try and retro-fit a TILT circuit.

All parts are here and accounted for. Instructions included but few enough parts that wouldn't have mattered. Takes a while to get here but it seems if I order one or two projects a week there is always one arriving and I am never without a project to do.

32K of EEPROM data over a serial bus, in a single chip! These are the PU27-D versions of the chip that work with 2.7V to 5.5V so Arduino, ESP32, whatever you want to interface these to will be a snap. I'm testing them using an ESP32 (3.3v) and they are working fine. Jumpers are for 3x addressing, 1x WriteProtect so if one isn't enough, add up to 7 more. Work well for storing run-time data where other options might be an SD-card. Official LC Technology branding on these modules

These boards are the best bang for the buck of micro-controllers with the only gotcha being that there are 38-pin and 36-pin versions with completely different pinouts. If you don't care it doesn't matter but if planning on building more of a designed project (count the pins before you order). Nice that the pins aren't mounted for projects where you only need a few connections to the board and can wire it directly.

These are very sharp and ground down to easily cut flat against the PC board. Written on side of handle: "MAX DIA <= 1.0mm COPPER WIRE". Maybe not Titanium but very well built, I will be buying more of these.

These are very solidly built and well insulated screw terminals with pin spacing of twice the standard 1/10" allowing connections of high voltage/current devices. Most readers will already be familiar with these connectors since the majority of application modules use these for connections.

Smaller thread than I was expecting but I was pleasantly surprised on the quality. Nice assortment of both spacer posts and mounting posts. Hardware smaller (matches thread), but fits nicely in tight spaces on small boards. Very strong, don't let the scaled down size fool you. One of the best deals in PCB mounting hardware on Banggood!, at a fraction I would pay at a regular supplier.

Came in a big bag of unlabeled boards so it took a day to sort through and google what they were. If you are an Arduino fan and haven't yet tried some of the available modules this can save you some time and money. P.S. Banggood is getting back on track with delivery times, fast delivery.

Handy to have a prototype with built-in stereo volume and some supply filtering (a must have) but the 'USB' descriptor is totally misleading and seems to imply that its USB powered.. with NO USB CONNECTION. It can use 2.5V to 5V DC power but nothing USB about these units.

What was delivered was 2 speakers clearly marked 2Watt that looked nothing like the picture (black cones). Very light weight, small magnets, low output, with very narrow bandwidth. Better speakers available for same price range, shop around.

Looks like a very good quality module but unfortunately project on hold so I can't evaluate it's performance. Microphone, SD card reader,.. good all-around MP3 I/O encoding/decoding utility module. Working on FM radios interested in Internet Radio, and this module is a good interface to Internet Radio. Hope to get it on the bench soon.
