Karabas Mini / Mini G

Rev.G2

• replaced UDA1334A with PCM5102A
• aligned SDRAM tracks

Rev.G

• removed crystal from FT812
• removed MCU_IO4 connection from RP2040
• the MCU_IO4 line now repurposed as FT812 8MHz clk generated by FPGA
• disconnected FT_AUDIO, FT_DISPLAY from FPGA
• PWM audio replaced with UDA1334 DAC
• disconnected FT_PD from FPGA, connected to RP2040 as FT_RESET
• disconnected MIDI_CLK from FPGA, replaced with 12 MHz crystal
• disconnected MIDI_RST from FPGA, connected to RP2040
• disconnected ESP_BOOT and ESP_RESET from FPGA
• connected ESP_RESET to RP2040
• connected FT812 GPIO0 and GPIO1 and FT SPI to the uBUS header
• connected free FPGA pins to the uBUS as I2S slave pins
• added optional diode to the HDMI 5V line
• rerouted MCU_SCK, ADC_BCK and FT_CLK to the FPGA globak clock pins

Warning: Due to so many backward incompatible changes in the Rev.G, a dedicated firmware (_g.uf2) and cores (.kg3) will be released for this revision. Do not try to install the default firmware and cores (kg2) on this revision!

Rev.F (F1, F2, F3)

Rev.E

• Skipped

Rev.D

• Small improvements to the rev.C

Rev.C

• Initial Revision

Rev.A, Rev.B

• Unreleased due to broken FPGA pinout
