DescriptionThis low-cost mini USB CH341A 24 25 Series EEPROM Flash BIOS USB Programmer is intended to support 24 EEPROM and 25 SPI flash 8pin/16 pin chip. It is equipped with CH 341A chip, can automatically recognize 25 series chip, and its 24/25 series indicator lamp enables the user to easily recognize modules working status. This awesome programmer is also user-friendly because it supports USB to TTL conversion and the SOP8 SOP16 to DIP8 converter board makes the connection with different chips easily.CH341 is a USB bus convert chip, providing UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through USB bus. In UART mode, CH341 provides alternant rate control signals such as serial transfer enable, serial receive in ready etc. It also supplies common MODEM communication signal in order to expand UART forcomputer or upgrade common synchronous interface device to USB bus directly.In printer port mode, CH341 supplies standard USB printer port which compounds USB relevant protocol and Windows operating system used to upgrade ordinary parallel printer to USB bus directly. In parallel mode, CH341 gives out 8-bit parallel in EPP or MEM mode. It can be used to input/output data directly without MCU/DSP. Besides, CH341A also supports some common synchronous serial such as 2-wire (SCL, SDA) and 4-wire (CS, SCK/CLK, MISO/SDI/DIN and MOSI/SDO/DOUT) interface.You will require Combo Tool app for performing:Writing & Executing JavaScript in Android device and performing I/O directly.Plugin IR_Temper Sensor => Combo tool change to be a temperature meter.Plugin RS485 Converter =>It can capture/send RS485 Modbus frame.Plugin => It can be a UV meter.Features:USB interfaceWith CH341A chipSupport 24 EEPROM and 25 SPI flash 8pin or 16pin chipWith 24/25 status indicator lampSupport USB to TTL conversion Support 24EEPROM and 25 SPI flash 8pin/ 16pin chipRecognize 25 series chip automaticallySupports download STC series procedure of single chipSPI pin to support expanding the utilitySTC microcontroller supports a full range of program downloadSupport expanding the utility by SPI pinWith SOP8 SOP16 to DIP8 converter boardUsed in wide applications PC motherboard, LCD monitor, DVD, router program reading and writingSupports Windows XP, Vista, Win7 and Win8 (32/64bit) systemProvide 5V-3.3V power supply outputSpecifications :-Model: CH341A 24 25 SeriesMain Chip: CH341ADimensions: 85mm x 28mm x 12mmWeight: 20gmPackage Includes:1x CH341A 24 25 Series EEPROM Flash BIOS USB Programmer2x Header pins1x PCB board
