The race is on with the big players in the development board design arena sprinting towards that first viral ESP32 development board launch that will suit almost everyone out there!
And this time it is the nano32 by MakerAsia and Gravitech,
The nano32 development board
MakerAsia recently tweeted a new ESP32 development board that we have not come across before. Here are some images for you from the Twitter channel.
The nano32 definitely seems to be a very general purpose development board, similar to the Arduino Nano - just that the ESP32 can actually deliver a whopping 650 DMIPS. And not to forget high speed Wi-Fi connectivity and Bluetooth radio.
A closer look
Lets take a closer look at what the development board features!
Starting from the left of the top view of the board, we can observe the following right away:
- They have a ceramic chip antenna! Is it any good? It is pretty good for compact designs. It might not be as good as an external antenna though.
- There seems to be no IPX antenna connector for an external antenna - just in case that bothers you.
- There is no "ESP32 module" involved in this design - which means that the Nano32 is serious about cutting costs down - good news!
- The flash chip will hopefully be of the maximum supported capacity for the ESP32 - even if not, you can whack it right off and replace with your own flash!
- No shielding - this may actually matter depending on what project you use the board in and what other components you have in vicinity of this board.
- There seems to be a CP2102 chip for USB to UART bridge. The chips are actually really good (better than the CH340!).
- Seems like there is a polarity protection diode?
- There are probably 2 LDO regulators! We wonder if that has got anything to do with providing 1.8V for SDIO, etc or if the two are just separate 3.3V regulators to eliminate digital noise? We will have another followup article once we have more information.
- The microUSB connector is a good choice over the miniUSB connector (which is not very popular anymore).
- There is an EN and a IO0 button. More on the functions once we have our ESP32 tutorial series ready!
Get ready for the ESP32
The nano32 will be released in the next week (around 20/09/2016 maybe?). Though it will probably take a while for it to reach the markets, it is definitely good to get started with setting up the toolchain for the ESP32. We now have a Getting Started with ESP32 tutorial series!
