AZDelivery 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!

work very well

My use case was to program the ESP32 CAM Module I 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.

I bought a pack of these to flash an ESP32-based Sonoff smart relay, after having tried a CH340G-based adaptor that turned out to be defective. The first FT232RL adaptor I tried worked fine, and was detected automatically as a COM port by Windows 11. Pros: A jumper lets you select 3.3V or 5V data output, so you don't fry delicate 3.3V devices. All the main comms lines are broken out to headers (RTS & CTS, as well as the normal RX, TX, Vcc and GND), and there are lots of handy through-hole connections for other lines. Cons: No Dupont or USB cables included, and the connector is Mini USB, rather than the more modern Micro or USB-C, so it's harder to find an appropriate cable. The screen print on the board is very close to the header and jumper block, so it's hard to see which cable is which. Although the adapter worked fine for flashing the Sonoff device, it couldn't supply enough power to allow the ESP32 to fire up a WiFi connection.

Good

Excellent product. The reason I gave it 5 stars is it comes with pins already soldered and it has a simple jumper to switch between 3.3v and 5v as opposed to most FTDI where it's a solder jumper. It worked great once I figured out the mini usb cable I had lying around only had VCC wired. It was plug and play on Win 10 64 bit.

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.

It works just fine on Linux Mint after I installrd the software for it but have not been able to get it to work on Windows 10 yet.

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 Mini Gnd ---------Gnd 3v3 NC 5v -----------5v Txd----------Txd Rxd----------Rxd DTR----------DTR

J'ai utilisé ce chip pour envoyer des messages de mon PC (windows) vers une raspberrypi4 (UART). Il y a un dumper pour sélectionner le voltage. Par défaut il est place à 5V. Il faut faire attention à placer le jumper pour avoir des TTL à 3.3V. Le port s'installe automatiquement.... Il faut attendre un peu une fois qu'il est connecté. Dans le gestionnaire de périphériques, au début, le port n'est pas défini. Après un certain time, on a le port COM3 configuré. Pour le moment je suis content....

Aucun problème, directement reconnu par Windows et la liaison série fonctionne parfaitement.

perfecto funciona con w10 sin problemas

Sehr guter Wandler von RS232 TTL Signalen. Mit einer kleinen Adapterschaltung mit einem MAX 232 konnte ich sofort meine alte Anlage damit an den neuen PC anbinden der keine RS232 Schnittstelle hat. Treiber wird im WIN 11 automatisch installiert und sogar mit UPDATE versorgt. TOP!! Hab sogar nachgekauft weil man damit mehrere Anlagen gleichzeitig betreiben kann. Für jeden Stick wird automatisch eine eigene COM angelegt. Nur bei der Zuweisung musste ich manuell eingreifen da meine alte Software nur COM 1-4 unterstützt.

Funktioniert tadellos unter Ubuntu Linux. Es sind keine zusätzlichen Treiber notwendig. Einfach anstecken und /dev/ttyUSB0 öffnen. Mit den seitlichen Stiftleisten eingelötet passt der Adapter perfekt auf ein Steckbrett und versorgt einen Mikrocontroller mit Strom (wahlweise 5V od. 3.3V) und einer USB Schnittstelle (TTL-RS232). Praktisch wenn man beim PC kein Labornetzgerät oä. zur Verfügung hat. Auch toll wenn man eine Schaltung mal schnell mobil von einer Powerbank versorgen möchte. Wieviel Strom man aus der Versorgung ziehen kann konnte ich aber nirgends lesen. Für einen Controller und ein bisschen Peripherie reichts bei mir aber. Schade nur, dass der Adapter keinen Micro-USB sondern einen Mini-USB-Anschluss hat. Micro-USB-Kabel sind leichter zur Hand, Mini-USB ist aber wahrscheinlich auf Dauer robuster.
