✨ The Juno FDxICSP is the world's fastest SPI programmer for AVR microcontrollers. This is an extreme premium-quality project both in the PCB design and the custom firmware. FDxICSP is also a programmable programmer, making it easy to adapt to any other system. The current programmer firmware is based on an antique AVR910 protocol, yet, I still manage to get this to achieve a world-record of 28.3kB/s write speeds. The bootloader that allows it to be self-programmable is also my own work that is based on the AVR109 protocol, and again achieves a record high speed. In short, all these functionalities reside on a single pre-programmed MCU, so it is a chicken, an egg, KFC, Chick-fil-A and more in one mini package, as you will.

🔑 FEATURES & SPECS
✓ World-Record SPI Speed - 28.3kB/s write & 32.2kB/s read (benchmarked on ATmega128 at 2Mbps)
✓ AVR910 MOD - Supports 90%+ AVR MCUs ≤128kB via signature-byte decoding
✓ AVR109 MOD: 15.8kB/s write & 27.2kB/s read (ATmega88)
✓ CH340G USB Interface - 2Mbps throughput (500kbps bootloader/1Mbps programmer default)
✓ Dual Voltage Operation - 5V/3V selectable with solderable jumpers (pick one only)
✓ All CPU clock supported - Auto-SCK 4MHz-488Hz + devcode overrides (#1-7:8-14 Hardware:Software SCK)
✓ RGB Status LED - Blue (flash write), teal (EEPROM write), pink (read)
✓ Tiny high quality PCB - hand-routed board and crafted layout front and back
✓ MCU coded by a C/C++ and embedded expert - Every line of code is written by me
✓ Note: MOD means completely rewritten from scratch. Achieving the fastest speed using the oldest protocol is not easy.

🔧 PERFECT FOR
→ Programming an AVR MUC at top speed (You would save a lot of time using this programmer.)
→ Beginner and intermediate SMT/SMD/THT soldering practice (This is a fun mini project.)
→ Advanced AVR microcontroller programming projects (The board can be re-programmed into anything.)
→ AVR Programmer and Bootloader development (The board can be re-programmed into another programmer.)
→ STEM/electronics education (adults & experienced teens)
