To connect the ch341a programmer with sop8, you will need to first use a soldering iron or another heating device to solder the necessary connections from the SOP8 package onto the board of the programmer itself. Although this guide wasn't what solved my problem, it was rich with information and gave me the tools I needed to get where I needed.

I got one of these today, and I noticed the PCB layout of mine is different compared to the one posted in this forum by jakeisprobably.Otherwise, if you are programming in circuit, simply make sure your test clip lead includes 10K resistors in series with the /HOLD and /WP pins. Con el adaptador de gran formato puedes utilizar este adaptador para poder usar un ordenador a la vez que se conecta a internet, o a otros dispositivos con puerto usb, como por ejemplo una memoria flash o una tarjeta gráfica. that there is yet another fault in the design to reset / set the QE bit in the second status register. Yo he pedido el CH341A , y en su lugar me han enviado el CH341B , el problema es que no se si tiene las mismas caracteristicas de voltajes y conexiones y de si se usa el mismo Software . It is a small, portable device that connects to a computer via USB and can support a wide range of chips, making it a versatile tool for electronics enthusiasts and professionals alike.

The headers that were provided with the 16 pin chip clip included an 8 to 16 pin as well as a 16 to 16 pin header. Double check to make sure you have selected the correct chip, as programming the wrong chip can cause permanent damage to the device. We are creating a video content on YouTube, and we are referring to the schematic of Mini Programmer CH341 in this post.Additionally make sure your User-Agent is not empty and is something unique and descriptive and try again. I wasn't confident soldering the chip and de-soldering it again onto the adapter, so instead I took the spring out of the clip and put the bios chip as deep as it would go into the clip and closed it manually. Any resistors bigger than 0603 will be problematic due to the limited space between the Vcc track and the /Wp pin.

pin 24 of 341A (translated with Google): "Chip function configuration output, built-in pull-up resistor, can be connected to the serial EEPROM configuration chip SCL pin". or different than ID too, like BIOS ends in FV sometimes BV works better, but you'll figure that out later if it comes to that. What’s the fault with this firmware- there are some posts of you 2 years ago, but I won’t read them all since this might no longer be the problem. The latter are signs of a 'dry' (bad) joint, too much solder and either movement while it cooled, not enough heat or a lack of flux, maybe due to carrying * the solder to the joint on the bit so the flux core burnt off before it got there - Always apply the solder to the work, never to the bit (except after wiping it, the bit needs a tiny drop put on it for good heat transfer).CH341A USB EPROM programmer for burning BIOS, SPI, FLASH, 24 and 25 series memory from various manufacturers. The reason it's usable at all is that it has 5mA current limiting on MISO, MOSI and CLK pins, not mentioned in the datasheet, but you can ascertain yourself. Cuando necesite más ayuda para encontrar los programador más populares, todo lo que necesita hacer es ordenar por pedidos. Is there a way to get a known working version of my bios or a fully modded one for me to attempt a flash?

Esté siempre atento a las múltiples promociones de programador en AliExpress, para que pueda comprar programador a precios aún más bajos! Note: Due to the characteristics of the CH341 chip, the ESMT SST class 25 chip can only be read and cannot be written. The ZIF socket has 16 pins so it is divided in half with the right side for 24xx chips and the left side for 25xx chips.I'd just like to thank the original author for providing the schematics, and all the other useful information for a newbie like myself. Therefore, I grabbed the datasheet for the MX25L6445E SPI chip and looked at the pin diagram and identified the type of package that is installed on the WNDR3700 circuit board. I strongly recommend practicing adding mod-wires to scrap boards, and also removing and replacing components on them to improve your skills before you work on anything valuable.
