The Battle of the ESP-201 Giants

ESP-201This is a relatively new one – the ESP-201 – larger than other game-changing miniature WIFI boards (or miniature powerful programmable devices with WIFI as you prefer)  but with one big advantage – unless I’m mistaken this new WIFI board (which will be functionally identical to others as it has the same parts) appears to have 0.1” spacing which means for the first time other than the pin-challenged ESP-01 we’ll be able to experiment with this board on normal breadboard or with normal prototyping wire – and that has to be a good thing.

The only question is – do you want to pay £3.29 or £2.58 (that’s Pounds Sterling as I am UK based)

Here they are – if anyone has any CHEAPER links do let me know…

These boards like the others run on 3v3 and like some of the others have an on-board antenna – but there is also an option for an external antenna (I’ve not found the need for one myself).

The point is – unless SIZE is a big issue, these almost compete on cost-price alone with the ESP-01 but without the pin restrictions – let’s see what we get – and if anyone has done some work with one of these could they please let us know how these pin-mappings compare to somewhat more conventional pin names for these devices.  I expect I’ll have mine soon and am looking forward to taking the opportunity, perhaps even at the weekend, to mess with second UART debugging, I2C and a host of other features denied to ESP-01 users (except those with obscenely accurate soldering skills and very fine wire). Mind you, a planned BURNS night on Saturday might slow progress a little.

  1. These look very nice except for the four uart pins – why the hell are they pointing down, not up. This makes them hard to use with breadoard.

  2. I considered this board then chose an ESP-12 with breakout PCB. Both look to have the same problem of being too wide for breadboard. Actually, my PCB does fit a breadboad but only just, leaving no space to connect to it! I ended up soldering the header pins to the wrong side of the board (tricky) so that I could see the legends and use male to female jumpers to connect to the breadboard. This board looks like its legends are on the same side as the pins so that woud work better.

    • still beats the very narrow gauge found elsewhere. Something for everyone. I did think of doing my own boards but could not get the chips as cheap as the ready made boards.

    • Oh well done- nice clear article – mine has not turned up yet but it looks like it’s going to be worth the wait – at last an easy to use module with 0.1″ pins.
