R1000AX and R1001 are Off to Production

Hello Everybody, I have a quick update this week:

Thanks For Making It Happen!

I know that’s a little late (we were very busy bringing up R1008), but thank you all very much for supporting JuicyBoard. We got a lot of constructive feedback that added positive features and modifications to the design.

R1000AX And R1001 Are Off To Production

A little over a week ago we submitted R1000AX and R1001 gerbers to our Shenzhen manufacturing partner, we’re expecting production samples in another week. So far so good. We’re planning to submit the order for the rest of the boards on Monday next week. We will keep you posted with manufacturing progress.

R1008 Bring Up Is Complete

That was the main focus in the past 2 weeks, R1008 is bringup is now complete. We have the 1st version of the on-module firmware, with our test setup we were able to measure 2 RTD elements through 2 different channels within 0.2C relative to each other and 0.4C compared to an external temperature sensor. We estimate the absolute temperature measurement accuracy can be +/-0.5C over 0-300C but we have to measure this with a carefully calibrated setup, which is what we will do over the coming weeks. R1008 gerbers will be sent out to manufacturing with the rest of the boards next Monday.

JuicyBoard R1000AX

This is the JuicyBoard with all bells and whistles! 15 feature slots + SD card slots + all the reliability and safety features.


$19

R1001 Smart Stepper Motor Driver

Smart stepper motor driver module with independent current control, stepping resolution, and telemetry functions.


$9

R1002 Quad 1A DC Low Side NFETs

Quad switches for controlling low-power peripherals, such as large LED status displays and fans. Maximum current limit of 1 A per channel.


$5

R1003 Analog/Digital I/Os

This module provides a quad channel analog or digital interface to the main CPU. It includes a 1% 4.7 kΩ resistor as required in most thermistor setups. Can be used for analog inputs, digital inputs, or outputs.


$15

R1007 Quad 20A DC Low Side NFETs

Four super-low resistance NFETs that can be used to drive very large peripherals (like a large heater or DC spindle). The transistors are rated 100 A (with less than 2 mΩ series resistance). Includes the necessary R1005 extender module.


$39

R1008 Dual-Channel Platinum RTD PT100 Temperature Sensors

This module uses two Maxim MAX31865 RTD-to-digital converters for precision temperature measurement. Hook up two PT100 resistors appropriate for your application (not included) for temperature readings accurate below +/- 0.3 C. Can be configured to sense 2-wire, 3-wire, and 4-wire PT100 configurations.
