The BT-FLASH USB-C Interface Tool by bloomtec, is a professional-grade adapter engineered for console modification work (flashing/dumping), diagnostics (syscon), callibration (PMAP), low-level debugging, and automated hardware manufacturing. Whether you are flashing custom firmware, analyzing data lines, or running diagnostic traces, the BT-FLASH provides reliable, direct multi-protocol access from any modern PC.
Centered around the WCH CH347F high-speed USB bridge, the board translates USB into high-speed JTAG/SWD, SPI, I2C, and dual UART channels. Its onboard Amphenol 20-pin edge connector (quality part using in SFP sockets) allows it to function seamlessly as a production programming jig that mates directly with programmable bloomtec modules or your own designs. Built on a robust 4-layer purple FR-4 PCB with an 8MHz precision crystal oscillator and regulated 3.3V power architecture, the BT-FLASH delivers clean signals and dependable performance for hobbyists, workshop environments and batch production lines alike.
Features
Versatile Multi-Protocol Support: Provides direct computer-to-hardware access via concurrent JTAG/SWD, dual high-speed UART, SPI, and I2C interfaces.
Production & Service Integration: Built with a right-angle 20-pin 0.8mm edge connector, acting as a streamlined production-line tool and flashing jig for programmable bloomtec hardware ecosystems.
Powered by WCH CH347F High-Speed Controller: Leverages a robust high-speed USB bridge chip supporting 480 Mbps USB 2.0 communication and flexible multi-voltage I/O.
Stable Power Regulation: Features an onboard Texas Instruments TLV75533 3.3V LDO regulator alongside low-ESR Murata and Taiyo Yuden ceramic decoupling capacitors for reliable, noise-free logic voltage delivery.
Professional Build Standard: Engineered on a compact 4-layer purple FR-4 PCB (1mm thickness) with a lead-free HASL finish for high-frequency signal integrity and long-term durability.
