    STM32F103VET6 und CH340R

    pegel wrote in post #6114747: > Sicher, dass der CH340 das nicht intern macht und keinen R braucht? > Habe noch keine Schaltung mit R gesehen. Das bezog sich auf den USB der direkt an den STM geht. Der CH340 sollte das eingebaut haben.

    Cant' upload sketch to Nano V3.0 + Atmega328 CH340 because programmer is not responding

    tried to upload the sketch to a more minimal board. I chose a non-original Nano V3.0 mit Atmega328 CH340 (https://www.az-delivery.de/products/nano-v3-mit-ch340-arduino-kompatibel) and I connected it via USB directly to my macOS computer that runs the Arduino IDE v2. Unfortunately, the upload of the sketch

    Check the Schematic Atmega328P with LoRa

    Your power supply isnt valid with the last changes. V3 of CH340 needs input voltage in 3V3 Mode. It is no output. So you have to generate 3V3 from your USB or the battery (see attachment CH340 or datasheet). If you need an integrated 3V3 regulator, take a look

    Custom ESP8266 Board unable to connect

    supply voltage 2. measure the supply voltages on the devices supply pins 3. bridge rx and tx at the CH340 and check it with a terminal programm 4. .... 5. .. > Any help is gratefully appreciated. The pins in good readable schematic symbols are not sorted in the package order. Instead they represent

    device. For Programming I am using the LOLIN D1 mini for the board and I have correctly installed the CH340 Drivers, I also tried six different USB cables and the GPIO0 is effectively tied to ground when trying to flash. I attached my design, if anyone wants to thinker with it, have a go, and let me know

    ATmega328 + ESP-01s low power brainstorm

It then compares that value to a calibrated value to decide whether the plant light should be on or off. This then gets sent by means
