Youmile USB Programmer Series Burner Chip 24 EEPROM BIOS Writer 25 SPI Flash + Sop8 Test Clip

Product Information

Maybe these videos will make it clear that without the recommended mods how casual use without consideration for proper voltage levels to the target bios/memory chips could lead to a disaster. Su satisfacción es nuestra primera y principal preocupación, y es nuestro logro en nuestro sitio web. I have a CH341A Pro black "edition" and I tried to read some chips using clamp (chips are on board soldered), first the Detect doesn't work - ok china - i have selected the correct chip from list and read the chip. Dupont wire is not included) Directly connecting MSI mainboard to flash is available with SPI pin which is corresponding to MSI JSP11 port.

Any resistors bigger than 0603 will be problematic due to the limited space between the Vcc track and the /Wp pin. I could solder wires onto the functioning pins of the MX25L6445E and interface it to the CH341a Zero Insertion Force (ZIF) socket but since I could use a 16 pin chip clip for future engagements I decided to purchase one. Carrying solder on the bit for as short a time as possible is permissible, indeed necessary, for certain specialist techniques (e. After downloading the software and installing it on my Windows laptop, it was time to pick a target. Modification 2: Add a 1000uF 16V elco capacitor to the USB power line, positive side of capacitor goes to the plus pole, and negative side of capacitor goes to the minus pole of USB power line.

Disassembling and burning: For larger motherboards, you can remove the BIOS chip and burn it separately. I will upload a well commented version once I have added these comments for better reading and unstanding. I dont have a previously saved good BIOS file, I backed up what was on the assumed corrupted bios chip using flashrom but when I read that in FD44 its blank. Run the programm, now there are no 95xxx type of eeproms available in the software, select 25xxx, with same capacity as your chip.

Here we will provide you with the Software for your programmer and all other details related to the CH341a Universal Programmer. reg is used to power USB so the USB interface operates at reduced voltage without this connection because of losses in the internal regulator. EXE - self installing archive with multiprotocol interface driver ( this one is for the programmer mode). For improved reliability and to avoid burning memory chips, I highly recommend using a level shifter. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.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. ACT remains at 5v after I get that message on host PC (also at 5v when I plug it into a USB battery i. A quick look at the board reveals the main electronic parts used: CH341A, a 12 MHz crystal required by the chip, a 3. 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. Could someone please confirm if upon connecting to a USB power supply there should be immediately any voltage at all on MOSI or MISO?

I was also trying to get a working BIOS on the machine so that I could have flexibility when booting, e. Allí encontrará mucha información útil y útil sobre programador e incluso consejos para hacer que su experiencia de compra sea increíble!I considered creating a voltage divider to step the voltage down but after a little Googling, I came across the CH341a with the 1. 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. IF* you need the capability to program DIP-8 package SPI FLASH chips with non-volatile quad SPI mode, and to be able to enable that mode with the chip in the ZIF socket you need to do the mod. The programmer can be bought with additional sockets and adapters, some of them with voltage shifting circuits.
