ເນື້ອໃນ: [Dobrica PavlinuÅ¡iÄ's random unstructured stuff]
ນີ້ແມ່ນອຸປະກອນ 5V ໂດຍບໍ່ມີການດັດແປງ! ມັນເຮັດວຽກສໍາລັບຂ້ອຍ (tm) ແຕ່ເຈົ້າໄດ້ຮັບການເຕືອນ http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/ພຽງແຕ່ຍົກເຂັມປັກໝຸດ 28 ແລະເອົາເທບບາງໆໃສ່ໄວ້ເພື່ອປ້ອງກັນການເກີດໄຟຟ້າລັດວົງຈອນ. ຫຼັງຈາກນັ້ນ, solder ຫນຶ່ງສາຍຈາກ pin ນີ້ໄປ pin 2 ຂອງ AMS1117 ແລະຍັງ C4. ດ້ານຂ້າງຂອງ C4 ເພື່ອເຊື່ອມຕໍ່ແມ່ນຫນຶ່ງທີ່ເຊື່ອມຕໍ່ກັບ CH341A pin 9.

ຮອງຮັບອອກນອກກ່ອງໂດຍ flashrom, ອາດຈະເປັນທາງເລືອກທີ່ດີກວ່າ, ແຕ່ຢ່າງໃດກໍ່ຕາມ:
