Adding code from @b-blake for minute support on alarm2 for DS3231. Includes status and aesthetic re-order of minutely and secondly.

test script used with metro rp2040 and stemma qt ds3231:

import time
import board
import busio
import adafruit_ds3231

i2c = busio.I2C(board.SCL, board.SDA)
rtc = adafruit_ds3231.DS3231(i2c)

# Set Alarm1 to trigger every minute
rtc.alarm2 = (time.struct_time((0, 0, 0, 0, 0, 0, 0, 0, -1)), "minutely")

rtc.alarm2_interrupt = True

def compact(t):
    t = str(t)
    t = t.replace(",", "")
    t = t.replace("'", "")
    t = t.replace("(s", "")
    t = t.replace("(", " ")
    t = t.replace(")", " ")
    t = t.replace("  ", " ")
    t = t.split(' ')
    u = t[0]
    u = u.replace("_", " ")
    t[0] = u[2]
    for v in range(1, 12):
        w = t[v].replace("=", " ")
        w = w.split(' ')
        #print(v, w)
        if   v == 10: t[v-1] = w[0]
        elif v == 11: t[v-1] = w[0]
        else:         t[v-1] = w[1]
        #print(v, t[v])
    print("{0:04}/{1:02}/{2:02} {3:02}:{4:02}:{5:02} {6:} {7:} {8:} {9:} {10:}".format(int(t[0]), int(t[1]), int(t[2]), int(t[3]), int(t[4]), int(t[5]), int(t[6]), int(t[7]), int(t[8]), t[9], t[10]))
    return t
    pass

while True:
    if rtc.alarm2_status:
        print("Alarm triggered!")
        compact(rtc.alarm2)
        rtc.alarm2_status = False  # Clear the alarm status
    time.sleep(1)
