Livano is a very small breakout module that supports programming via Arduino or SPI/PDI. You Can Programming via avr studio without bootloader. Also ADC Channel Pairs with Programmable Gain (1x / 20x / 100x).
AtTiny841 arduino stack and bootloaders are available Spence Konde repo. Thanks Spence Konde. please check
