AZDelivery 5 x compatible with FT232RL Mini USB to TTL Serial Converter Adapter Module 3.3V 5.5V FT232R Port DTR RX TX VCC CTS GND Pin compatible with Arduino and Raspberry Pi including E-Book!

These devices work to connect Arduino Pro Minis via USB to a host PC.However, the documentation suggests crossing over TXD and RXD lines, as might be expected. However, this is not so. TXD to TXD and RXD to RXD works.FT232RL Pro MiniGnd ---------Gnd3v3 NC5v -----------5vTxd----------TxdRxd----------RxdDTR----------DTR

Arrived on time and packed in a sturdy cardboard box containing an antistatic envelope surrounding the product itself. The product was quickly put into service flashing software onto an ESP32-CAM board which lacks the on-board USB-serial converter that most of today's microcontroller boards include.I plugged the module into a USB port on a Windows 10 laptop and, after a short delay, it showed up as COM7, no driver installation needed. Drivers for Windows, Mac and Linux are easily found on the Internet if required.I connected the serial and power lines from the module to the ESP board with DuPont wires and shorted out a link to put the ESP into download mode, then compiled and loaded the software via the Arduino environment. All went without a hitch, despite some of these ESP boards having a reputation for being tricky to flash.Cut/paste of one of the messages on Arduino console:"Wrote 902304 bytes (487502 compressed) at 0x00010000 in 11.9 seconds (effective 604.1 kbit/s)... "Conclusion: Does the job well, useful addition to the gadget toolbox.

I wish, was usb-c or micro usb, not old mini usb connection, but its works.

My use case was to program the ESP32 CAM ModuleI found the 3.3V line on these modules a bit underpowered to program the ESP32 CAM module (brown outs and errors), but there is a simple solution: Set the jumper to 5V and connect the power output to the 5V line on the ESP32 CAM. My guess is the ESP32 CAM uses a bit more power than intended for this module to supply.Otherwise a great product, does exactly what it is intended to.

Unsure of why my previous review was unacceptable. These units ( I bought 25 ) all report as FT232R. They work in Linux. Difficult to use more than one per computer with the ftdi library. This is because all 25 units identify with the same serial number - this makes it impossible to uniquely identify each device.Official FT232 chips are programmed with a unique serial number.

Worked for me on ESP 32 once I found a Mini USB cable that was not power only.Wiring FT232RL to ESP32RXD to TXTXD to RXDTR to GPIO0RTS to EN3.3v to 3.3vGND to GND

Needed this to write the firmware to the WiFi Board on a Phantom II Vision + drone. Worked straight away with no need for driver installation etc.Wired up to the WiFi board, fired up Teraterm and was working straight away!Couldn't fault this at all!Will definitely order from this seller again for any future needs!

I'm by no means an expert but these little devices seem to just work, as an interface between your computer's USB port and devices without one.So far I've used them to load firmware to an ESP32-CAM board, and to talk over TTL to a Modbus device.The devices arrived in good condition, in reasonable packaging, and the manufacturer/distributor emailed over a full datasheet when they received my order. Good value and I'm happy.
