But as an EE Engineer I dont recommend to use the circuit like that.Source: All Vcc connections in the ZIF socket are 3.3V but the CH341A is powered at 5V.So all I2C and SPI signals are 5V while the external memory is powered at 3.3V.
Serial Eeprom Programmer Schematic Series Resistors OnThere are no limiting series resistors on those signals. One simple solution to fix this issue is to simply bypass the 1117-3.3V regulator. I can use the hot air station to remove the 1117 and then short-circuit the input with the output. My question is, is it safe to just do the short-circuit without removing the 1117 linear regulator. Also, if you want to convert to 3.3V you should not only remove it but patch in a current limiter in its place e.g. Not sure what I got to do to make it run at 3.3v Lift a pin Can you please post a better top-down photo Thank you. Not sure what I got to do to make it run at 3.3v Lift a pin Can you please post a better top-down photo Just lift pin 28 and put some tape under it to prevent any short circuit. Then solder one wire from this pin to pin 2 of AMS1117 and also to C4. Lego indiana jones wii iso torrentThe side of the C4 to connect is the one connected to CH341A pin 9. But if not to lift that pin you have to heat up the solder first Please post another top down photo Thank you. The jumper is to select device mode: EEPROM programmer or serial converter. Everything you buy from Aliexpress or similar is a crappy clone of the original. In order to sell a low cost version of some device, they always use counterfeit parts and remove non-critical components. If someone creates an apparent compatible circuit that costs 1 cent less, they start to sell it under the same name and description of the previous device. Is there a Brand name you recommend The green one has been vetted on Win-Raid. What do you guys think of this product Its a Flashcat Programmer. I used my CH341A Black along with a SOIC8 Clip test adapter to jump start my dead Netbox back to life. Nothing got short circuited, the world didnt come to an end, and it just worked with out the 5v paranoia.
