Just got my SP03 module and planning to connect upto 12c, so using the 2-pin sda and scl connected TX/RX - I'll just use two spare output ports alongside a direct 5v accordingly? I assume 5v running on anything but the servo ports (and I'll have to specify the ports in robobasic). There's a fair bit of code using the 12c and it can be notoriously hard to run smoothly without creating a buffer in between data strings, otherwise the processor will be overcooked. I'm just looking to slave the SP03 and use basic commands to send text directly from the MR-C3024 accordingly.
Also, where exactly is the best place on the MR-C3024 to draw a direct 5v? I assume that 5v is the maximum voltage when the module is in use, or does it also run idle at 5v? It advises you to do a small solder mod, but I don't have the resource to do that right now....
There's very little support.

The SP03 works fine under I2C on the C3024. It is best to use the PWM pins, since they are rarely used and have 5V and can be accessed from RoboBasic.
Check the threads here for more information on bit banging, or my I2C firmware.
The only problem with the SP03 is the low volume from the rubbish speaker. Try changing it.

Hi
I've just remembered problems with the printed diagram with the C3024. Non the less, SCL > SCL pins and SDA > SDA pins and just draw 5v straight from the PWM? I see by the SP03 configuration that TX/RX is used for the RS232 , but I want to avoid RS232.
Good to know it works nicely on 12C, I'll give it a go today

NO! The SCL, SDA pins are dedicated to the Program EEPROM, so cannot be used.
You must use other pins for I2C, and either bit bang the protocal on those pins, or use my alternative C3024 firmware for a second I2C port on the PWM pins.
The PWM pins are available to use for the bit banging, or any free servo portscan be used.
