Question Anything wrong with connecting L298Ns in parallel? --- Answer Nothing wrong. Hobbyist do it. Engineers can also do it. It all depends on cost/benefit/risk hobbyist/engineer trade offs. Let me explain, starting with ULN2803, then L298N. *Part A - ULN2803A Case* [ULN2803A Darlington Transistor Arrays - TI][1] From datasheet - Section 3 Description The ULN2803A device is a 50V, 500 mA Darlington transistor array. The device consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. ***The Darlington pairs may be connected in parallel for higher current capability.*** --- *Part B - L298N Case* [L298N Datasheet - ST][2] By the same ULN2803 token, L298N can also parallel output for bigger current. Since the BJTs in parallel are from the same die, so they should very well self balance out their currents. --- [![l298n 1][3]][3] --- [![l298n 2][4]][4] --- *Part 3 - L298N Dual Full Bride DC Motor Driver Module Case* [AliExpress L298N Dual Full H Bridge DC Motor Driver Module - US$1][5] The very popular cheapy L298N motor driver modules are for driving two 4A DC motors. For a bigger motor, say 8A, we can parallel two drivers into one big driver. Warning: me just friendly hobbyist. No guarantee no nothing would melt down or blow up. --- *Part 4 - Discussion and Recommendation* [1]: https://www.ti.com/lit/ds/symlink/uln2803a.pdf?ts=1616825443744&ref_url=https%253A%252F%252Fwww.google.com%252F [2]: https://www.st.com/resource/en/datasheet/l298.pdf [3]: https://i.sstatic.net/3XMSr.jpg [4]: https://i.sstatic.net/wRe9r.jpg [5]: https://fr.aliexpress.com/item/4001175036525.html?spm=a2g0o.search0302.0.0.5ab31cc6QSHakX&algo_pvid=f71aa4cb-f623-4a20-b2ef-553c0ca9a2c1&algo_expid=f71aa4cb-f623-4a20-b2ef-553c0ca9a2c1-25&btsid=0b0a555416168995427627943e6913&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
