@jpilarski take a look at the I2C hub from Seeed; only problem is how many milliamps your I2C sensors need. My multichannel gas sensor (from Seeed) cannot run on the bus while the BME280 is on at the same time. btw addresses are configured properly.

So I still don't know does the m5go have 4mb of sram or does it only have 512k. Is the 16mb of spi flash where micropython is loaded or is it on the 512k of sram. Can someone verify the specs for m5go and if it works well with micropython based on these specs.

Question: do the 4MB of RAM eat noticeably more power?

No.
Is barely noticeable...

Python is quite a memory hog compared to C/C++, so definitely go for the 4MB of RAM if that's what you want to do. If you're developing/prototyping for environments where that's not available, then maybe don't get used to it.

Are you sure the m5go has 4 mb of sram and not 520kb as listed on Amazon. Also what are the ram requirements for running blockly/python and why is it so beneficial to have 4mb of psram as on the new fire board. I am trying to decide which to purchase m5go or fire. I wish all of the sensor modules were sold separately in particular the i2c hub expander.

@kurthofman Hi Kurt,

M5GO vs M5Stack Grey PSRAM / MPU9250 model - Many things are the same but some things are different. Here are the major differences:

M5GO - 16 Mb SPI Flash , 4 Mb SRAM , 3x Grove ports , 550 mAh built-in battery, includes screws connecting bottom to top - 2 are captive, Lego compatible surface on the bottom module, RGB LEDs built into the bottom module. Comes loaded with the M5GO firmware that includes the Blockly web programming program.

M5Stack Grey model - 4 Mb SPI Flash , 4 Mb PSRAM , 1x Grove port , 150 mAh built-in battery, no screws included, no Lego compatible surface on bottom module. Comes loaded with the "Factory Test" sketch.

The M5GO should support any of the add-on modules..... I tested it with the Battery Module and it worked fine.

You might want to purchase from the official store locations either at Ali Express here or their own store here
