as expected from arduino boards are easy and cool.
I ordered a set of 3s BMS, but my order never arrived. So I ordered again and the second one also didn't arrive. So now I paid twice, but still don't have anything to show for it.
Depends on what u want to do. This unit has power issues, wifi signal issues, camera only sends 2nd last frame issue, etc etc. Sigh, for simple things it’s ok. For more complicated task u want to look at a Pi Zero2W with camera mod 3 instead. Steer away from this one if u don’t like debugging and getting frustrated.
Great little unit and you can use a lot of different configurations
Worked perfectly as described. Documentation very clear and easy to follow. Only negative is the board component labelling is Chinese but documentation drawings overcame that.
This arrived within 24 hours of ordering. Good price, good delivery. Thanks.
Prompt delivery.
Found my error. Initial development had been done on a Nano, did not work on a Pro Mini. I re-did everything, all's good now.
Exactly as described. Fast & efficient service. Thanks
This unit was purchased out of curiosity, to see if it could do the job. 
Having compared and tested others that failed to live up to expectations, or are just plain idiotic in design, this unit was quite the surprise, both in price, and function.
I've yet to test it with a proper 4 wire PWM fan, but even just using a three wire FAN, the results are impressive. 
The existing 3 wire fan has been throttled to half it's speed, and noise level. 
I'm assuming the Thermo lead is working as described.
The trick for best performance is to test the different dip switch settings. 
Also, if you don't want audible FAN Warning's, switch them off.
This controller also supports individual control for the first two fans, and the third uses the board defaults.
The only irk is making sure you have the right gauge wire and connector for the 12V power lead.
Failing that, you can just buy a set of standard PC 4 Pin Power Splitter Cables from Jaycar, and trim off the 12V lead, as required.
Prompt Delivery. Replacement for a well aged set of probes. 
Let's see if these also last a decade.
Prompt delviery. Ideal for lower AMP and Voltage testing.
Prompt shipping. Ideal for data backup and boot laders for SBC's (Single Board Computers)
Good value, includes 2MB PSRAM, pushbuttons are easy to access, heaps of IO.  Not sure what was burnt in on receipt, I just reflashed with micropython 1.25
Cons: no external antenna option (internal antenna is fine), takes up two more rows on the usual breadboard.
Great product, well-pric3d and prompt delivery.
Love it. Nice to have it all in a compact form. Do wish it has a camera plug in but i am working on a webcam
Great item, works as expected, sent quickly, very happy.
Great product is easy to work with and works as expected. Postage was quick. I would buy these again for my next project.
Was exact what we needed and works perfect
Fast Shippng - Happy *******
Great expansion board, it fits ESP 32 perfectly and provides a USB-C interface - all around a great expander at a great price.
