The five LEDs on the snap-off section should be wired "active high" A zohm resistor for Bank 2 supply so that the IO voltage can be changed. Releases No releases published. Would it be possible to re-arrange the "J20 Flash" header? Shift IO pins two positions right, add a 3.
I have chosen better buttons for the icebreaker. They have a better feel and are more affordable. The new button and footprint can be found on Aliexpress. They fit on the current footprint but it is not perfectly matching the pins of the new button. Then you can observe that the firmware works until you insert the connector to the end.
Also when you use "charging only" USB cable, the issue doesn't happen and the firmware works all the time. I tried to investigate the issue with a logic analyzer and found that SPI data lines are pulled up for a short period of time about 2. This behavior can be reproduces with a more simple setup.
The correct version for 3V3 is the 93 L C46B. According to the top solder paste Layer they should not get covered with solder paste. Note: We are not making this change for the V1. This issue is part of the V2. I have also compared prices of similar parts from other vendors. The STM32 turns out to be lower cost than any alternative chip with this kind of specifications.
With added bonus of being easily available from a lot of vendors on aliexpress. This issue is here to track the testing of that part. Close it if we decide not to go down that path, or we realize that it has some big flaw that is worth the 4x price difference of the FTDI chip. Or when we decide to use this approach and decide that this is our main path.
The current version only allows the async fifo mode wit the ftdi to be used. But the async mode is pretty slow. You can pretty much get the same throughput as just using the SPI mode. The sync interface however is much faster. But of course, needs more pin And a header. The suggested part is Lyontek LY68L It is available from lcsc.
The datasheet is here. In "This impressive flexible design by Sylvain Munaut a. The schematic states we are using the ice5lp4k that is obviously wrong. We are using ice40up5k. What is the frequency accuracy of the 12 MHz oscillator U7 on the Icebreaker board?
The schematic does not define the part number, is a BOM available somewhere? I was playing with an SPI and found out that sometimes there is a glitch immediately after data has been sent. There is an entire discussion about this here. Therefore during SPI communication a lot of signals will drop to approx 2. If you can Now check the D Luckily the connector D11 is empty, but this is pure luck Don't ever solder anything there At least on the bitsy version of the board.

Am looking to add an RGB led but want to be sure I'm ordering something suitable. Please add the following feature: A 10k? This should be fixed in the schematics and the docs. Thanks for considering this. Hi esden I was combing through your design v1. Replace J17 with a 3-way jumper.
I have not tried this but it looks possible. To show what I mean, for option 1 here is how it could work: Add test point: On F. Cu: Add pad to B.
