YAKESTYLE 1PCS 5v/3.3v CH340G Serial Converter USB 2.0 To TTL 6PIN Module for PRO mini NEW

Product Information

The power_saving_init() should be the first thing to be called at setup(), it will initialize all your pins to LOW. power_saving_sleep() will put everything to sleep, and wake up every 8 seconds. With these two, with the regular board (no bootloader modifications, with the power regulator on, etc) when sleeping I was able to achieve 3.24mA of power consumption, which is already pretty good considering it was draining about 10.2mA when fully powered on in the first place. This instructable is a combination of all options in one box and its built from over 90% recycled parts so its Eco friendly, hence the name. As said you can try rebooting your computer and see if that helps…I never had to myself for my diode laser but…I have had to for other driver installs so…can’t hurt. Computers are funny things. This is a simple guide that will teach you how to take the first steps with the BTE13-010 module, a cheap Arduino mini clone. We will go through the 4 basic steps necessary to get it working immediately and without problems: Look at the Fritzing diagram above or follow the instructions below to connect the Arduino mini clone to the Serial to USB converter: BTE13-010--------------CH340G

I would stay with Laser GRBL open for testing until you can establish connections with it since to me it is easier to work in for diagnostics. Once LAser Grbl can comm with the laser and comp then you can swap over to LB. Before starting, we specify that this tutorial can be used to learn how to install the drivers of the CH340G module (Serial – USB converter), on which the communication between the Arduino mini and the PC is based. I have that model, too. That board is a mistake by design. It was very infuriating to find out the power supply was changing, while the levels on the data pins voltage were always 0..5V. Simply put…the computer is not even seeing anything plugged into the comm port. trying to do any more communication is pointlesss. Like not getting a dial tone on a phone…trying to continually dial out is an effort in futility. In the IDE, go to File/Examples/Basics/Blink and load the sketch. If you have performed the previous steps correctly, the IDE should be able to communicate with the Arduino and upload the sketch. Eventually you will see LED 13 (on the board, blue) flashing once per second. Blue LED on board flashes once per second (with “blink” sketch)

I have also found that these drivers work fine when connecting the LoLin NodeMCU V3 to my Windows 7 PC (I had to do nothing, since I had already loaded the drivers for my cheap Chinese Arduino Nano clones). I suspect the same will be true for the Amica v0.9 (yellow or blue PCB) NodeMCUs (both considered out-dated) and the DoIt/SmartArduino brand NodeMCU V2. Both of these boards also use a WCH CH340G USB-to-UART bridge chip. keeping, as already mentioned, the Arduino inserted on the two connectors, solder the 4 pads in the corners. Why only these 4 points? Because the breadboard is made of plastic and excessive heat could damage it Often the FTDI based ones are preferred. The FTDI chip is very expensive in comparison with other USB to TTL bridges, but they are often preferred. So look for FTDI when searching USB to TTL. Often FTDI ones use fake clones instead of the genuine and expensive FTDI, so if it's too cheap then it's probably not genuine FTDI. I wanted to hide the USB serial and USB sound dongles in the box so I looked through my junk box for a USB Hub. I found a 4 port hub so I decided to add a USB memory key. The analogue header doesn’t fit because of the reset button. Use sandpaper to make the analogue header thinner.

So my first idea was to buy a (maybe isolated) USB adapter and putting it in a heavy enclosure with a selection switch that makes it very obvious the voltage was. The access points normally are running at 115kbit and will need reliable transfer for binary uploads. However, if you look at the CH340 datasheet, the same board can be modified to change both the Vcc and the data pins voltage from the same switch, but you'll have to cut a few traces and rewire. I modified mine, but can not find the schematic with the changes right now. It was only a few traces to rewire as seen in the pics, and now it switches both the power and the data levels. Turns out that the driver isn’t signed and in Yosemite, driver files must be signed to be used. There’s a command we can issue to bypass this. If you buy your own FTDI chip, go for something that has two serial ports, e.g. FTDI FT2232H, those are often used as JTAG interface with an additional serial port, too.

Arduino clones need specific drivers, different from the standard ones that come with the Arduino IDE The NODEMCU “Arduino friendly” pin names (D0 thru D8, plus RX and TX) don’t correspond with the actual ESP8266 GPIO pin numbers, so you have to make special arrangements to map the “D1”, “D2”, etc names to the actual GPIO pin numbers. There are a few ways to do this.

Another alternative is to buy the FTDI chip from a reliable vendor, so to be sure it is genuine, then wire your own. Here's an example of a FT232RL wired by hand to a 0.1 inch perfboard. As said in the introduction, in this step we won’t explain how to solder because it would make the tutorial too long and, above all, because we already covered this topic in our first tutorial. So, take a look at it if you want to know more about soldering. Be careful not to connect the TXD terminal of the BTE13-010 with the TXD terminal of the CH340G (or the two RDX terminals)! To find out why, read this clear guide from Sparkfun on serial port operation and connection.Then I saw level shifter like a TXB0104 - would that be something where I could simply connect RX/TX/VCC/GND on both sides and turn my brain off? The main difference between HamComm and FLDigi is that FLDigi can use a tone on the right channel to key the rig eliminating the need for a serial port to drive a relay that Hamcomm used. I recently posted an instructable for an FLDigi compatible interface. It was largely based on a Hamcomm interface I designed as a hand out for a Ham / PC Usergroup talk I gave in 2005. I wanted to try echolink and I found that this interface worked perfectly except Echolink likes the serial PTT option. Our sketch is based on the one found by default on the IDE and which is called “Sweep”, with the addition of a 16×2 LCD display that shows the value of the rotation angle of the servo. Basically, it rotates the servo and shows how much it rotated on the display.
