esp8266 core board, compatible with 12e

As we all know, Espressif Systems is the manufacturer of esp8266, and the commonly used esp12e/s/f, esp01, etc. are actually modules from solution providers such as Escinco and B&T. It is undeniable that the design level of these manufacturers is indeed relatively high, but sometimes we need to de-modularize. The shortcomings of de-modularization are obvious: the design is not professional enough. The advantages are not many . . . But if you have extra esp8266ex on hand, you can’t waste it, right?

Demodularization is a series, and this is the first edition, the genesis of the series. This PCB is actually compatible with esp12 and has no practical significance . The significance lies more in verification .

The only advantages of this series:

1. The welding method of esp12 is often half-hole, and the production price is high . Therefore, if the thickness is not high, you can use 2mm pins to overhead . Then, the esp module can have upper and lower layers, and the motherboard can also have upper and lower layers. There are two more layers of space for components, which is equivalent to a partial double-layer motherboard , which can enhance component density .
2. De-modularization can be easily customized (customized), and spiflash, antenna methods, etc. can be changed according to needs.
3. Can be much smaller than esp12, but the cost will rise
4. low cost.
