| The JGAurora A5S and A1 are new printers released in October 2018. They feature a new 32-bit motherboard developed in-house by JGAurora, using Allegro A5984 stepper drivers with 32x microstepping, delivering much improved printing performance over their predecessor, the [[a5|A5]]. Both of these printers also feature smart features like power outage resuming, and filament run out sensors. The A5S and A1 printers have large print volumes of 300x300x320 and 300x300x300 respectively. | The **JGAurora A5S** and **JGAurora A1** are new printers released in October 2018.

| The "download" port on the motherboard contains a JTAG SWD interface, but the pinout is completely non-standard. this will help anyone who wants to flash: | If you wish to flash the firmware but do not want to use the SD card, or if your bootloader is damaged, there is another way to flash firmware, using the SWD interface on the motherborad. Note: the pinout is completely non-standard, please see the image above, and follow the instructions below. |

| Connect this port up to an ST-Link V2 using jumper wires / dupont cables, and you will be able to backup and upgrade the firmware on the A5S & A1. I recommend NOT plugging in the 3.3V line, but instead provide power to the board via USB cable, and only use the data and GND lines on the ST-Link header connection. I recommend you use the [[https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link004.html|STM32 ST-LINK Utility (STSW-LINK004)]]. | Connect this port up to an ST-Link V2 using jumper wires / dupont cables, and you will be able to backup and upgrade the firmware on the A5S & A1.
