When I try to restore the wallet from its 24 seed words in any other wallet it returns that the seed words are invalid. My coins are stuck.
Edit: To be specific, some wallets report an INVALID CHECKSUM

Hello, I've followed all instructions to install the wallet but receive the below error msg at compile time:

Error compiling for board M5Stack-Core-ESP32.

The pin to unlock the device is used as the BIP38 passphrase to encrypt the private key. This could lead to unexpected results when the user tries to restore their mnemonic from another device. If the user forgets their pin, it could lead to loss of funds. For users used to hardware wallets such as Ledger or Trezor, this is not intuitive, as they would assume a forgotten pin will still allow them to restore from their mnemonic.

My suggestion is to store the private key rather than the mnemonic. Then it's possible to allow the user to set an optional BIP38 passphrase, that can be backup up offline along with the mnemonic.

Add two button press or combo of buttons to enter wallet from Tetris

It would be fun to see how much battery you have left.

Also i saw there are some other batteries that you can attached.

Still a bit confused how better is this one(https://m5stack.com/products/battery-module) than the one that comes with the grey m5.

The wallet should display the splash screen after the pin has been entered

When I open the electrumwallettemplate.json in Electrum, I am unable to see or send my coins.

Hi Ben, loved your project and been experimenting with it :)

Wanted to ask about the grey M5Stack version that is recommended. Is this because of the 9-axis sensors?
Are they used for entropy? I remember that Stepan mentioned that the Specter DIY random number generator collects entropy from users interaction with the STM board - so I was wondering if this is the case for the recommendation of the grey m5.

Thanks!

Hello Ben, when I uploaded the new version for the first time, I entered the pin directly after pressing the wallet button, although no wallet had yet been created. Of course, the pin entry failed because I didn't have a wallet yet. I have flashed the device several times, always with the same result. Then I tried to do a hard reset with a text file on a micro SD card and then the message "Wallet not found" came up. I then flashed the old version and it worked. I created a wallet, set a pin and carried out a test transaction and brought the software up to date. Everything works fine now. Wanted to share my experience. Thank you for this great project Ben!

Hardware wallets are meant to protect the user even against compromised companion apps. If the user has on his PC a compromised Electrum, that Electrum might show a benign transaction but ask an "all funds to the hacker" transaction to be signed by "coldcard". By just writing out the serialization, the user has no way of judging if the transaction is ok or not.

Please show amount, recipient and which derivation the change goes to.
