Introduction When you first receive your development board you will want to plug it into your computer. What happens when your computer doesn't recognise it? You become annoyed, frustrated and confused. So what to do? It turns out that these boards have interface chips or Integrated Circuits (IC) that require drivers so that they can communicate to your computer. Chip Identification So how to identify the interface chip This is a CH340 IC that can be seen to have 16 pins and in a rectangular shape. Instructions for installing CH340/CH341 drivers. This is a CP2102 or CP2104 IC that is a square shape. Instructions for installing drivers for CP210x

Review of HiLetgo® ESP8266 NodeMCU LUA CP2102 ESP-12E Internet WIFI Development Board. Introduction After ordering my package from Amazon.com.au it arrived 3 business days later. It maybe different from where you purchase the item. I opened the package to reveal that the condition was excellent. Condition Well packed with foam padding to protect the pins. Inside of a sealed Anti-static bag. Listing The listing on Amazon.com.au indicated that it was a NodeMCU board one of the advantages of using this is that it is well supported. Lots of documentation, circuit diagrams, pinouts etc. Inspection Breadboard friendly: Yes when placed on a prototype board it leaves one pin free on either side of the dev board, however, there is no pin labeling on the top of the board which is mentioned in the sellers description. Close examination of the board revealed no errors and is a clean board. USB to UART chip used: Silicon Labs CP2102 LiPo Battery sup...
