Cheetah 1.1b 32bit Silent Board Marlin 2.0 For CR10 Ender 3 PRO 5 upgrate Support TMC2209 TMC2208 UART BLtouch


Following the success of the Cheetah and very high demand, our stock of TMC2209 chip is very low, we will soon offer an alternative version with TMC2208, this will allow us to produce more units, faster, so there will be 2 versions that you can choose, with a temporarly out of stock for the tmc2209 version(When the arrival time of the TMC2209 chip is confirmed, we will inform everyone at the first time.)
This board will work as good as the TMC2209 version, as quiet.(Just no sensorless-homing function)
Designed for a single-head 3D printer, many interfaces are reserved for more features. Such as AC detection, filament detection, leveling with BL-touch or other sensors.
Compact size: 101.5mm x 72mm,Compatible with the ender-3 motherboard size
fully integrated all in one solution:
STM32F103 MCU (Run Marlin 2.0 )
CH340 for high speed USB serial connection
4X TMC2209 stepper drivers, Support sensor-less homing;4X TMC2208 stepper drivers,No support sensor-less homing
can be used with 7V-35V for motors / heated bed
integrated high precision power regulators (DC/DC): 5V 1A Max and 3.3V 600mA Max LDO

High quality, High temperature FR4-TG130 PCB
Gold ENIG finishing
Ender 3 PRO
Ender 5
1.Why use USB-TO-UART chip for USB?
We just want to give you a convenient way to update the firmware without having to think about which bootloader to use and how to jumper BOOT0&BOOT1. Also, if your board is already installed in the machine, the jumper setting is more inconvenient for you. So, by adding a chip that can solve the problem, why not do it?
2.Why does the USB power flow back to the PSU?
At the time of design, we thought that plugging in the USB is just to update the firmware, and at other times you will use the SD card for printing. Even if you use USB printing, it should be a short-time debugging. Even, we found that most of the 2560 boards did the same, and nothing went wrong. This should be a way of testing over time. Until TH3D promotes this problem in the whole world, I think this will cause confusion for many people, so I will solve this problem whether or not it will cause problems, and it was already solved on the 1.2a version.
3.The direction of the encoder is wrong?
First of all, this is not a hardware problem, we can adjust it through software, and it is very easy. Secondly, there is no fixed standard in this direction, and different people may not like the same. Finally, we have changed to the most favorite way, if you want to reverse, you can also set the firmware yourself. Note: In fact, our price is only the price of a hardware platform, we have never calculated the value of software, we think that as one of the contributors and users of marlin, we should follow the spirit of open source, make more people easier Get the convenience of open source. Instead of selling it with open source resources.
4.The screen displays garbled characters?
First of all, we should know that low-voltage signals are easily interfered, so we should try to avoid the screen line and the high-voltage and high-current lines being too close. In addition, our people usually have static electricity on their hands, and directly touch some electronic components, which may also affect normal signal transmission. So if it is just an accidental phenomenon and it will disappear after re-power, then don't worry. If it has been there, please contact us and we will deal with it according to the specific situation!
